All good boards are able to use a 1/4 PCI divider, so that'll be 33Mhz. Most drives should be able to reach 40Mhz, that's 160 so no problems there.
I don't know which motherboards are the best, but I've allways liked the idea of OCing in steps of 1Mhz (can't remember which boards can do that).
i would suggest the asus cusl2-c nothing onboard, and has those 1mhz fsb increments you want. as with all the intel i815 chipset motherboards, the cusl2-c is able to run 133mhz fsb with the proper dividers for the pci and agp bus.
personally, i use an abit sl6 (i815). it is a good board, just that it doesnt have the 1mhz increments. been running my 700e@933 for the past year

Happy with my BX133Raid though now BX really is on its last legs, still lets my 700e go up to 950ish(prolly the limit of my cb0). Current decent hard drives, such as IBM's should be tolerant to at least 37mhz, and i know for a fact i've run mine at 40odd pci, though i wouldnt like to leave it there.

If you don't mind spending a bit more, get the Asus CUSL2-C Black Pearl which has the same performance as the regular CUSL2-C plus better looks to brag about especially if you have a modded case with plexiglass. http://www.asus.com/products/Motherb..._bp/index.html
The Intel 815E/EP officially supports the 133MHz FSB so it has a 1/4 PCI divider which makes the PCI bus running within the spec of 33.

Be aware of one fly in the ointment with that Asus board. The 1/4 PCI divider kicks in at exactly 133 MHz. If the CPU you select won't go at 133 MHz, you'll have to drop down to 120 MHz or so to get to a reasonable PCI clock rate of 40 MHz. At 129 MHz, for example, the 1/3 PCI divider would set the PCI at 129/3 = 43 MHz which is problematic for IDE hard drives and some PCI cards.
On most VIA 133A and BX boards, the 1/4 PCI divider is automatically invoked at 124 MHz. But with those whacky i815e ratios, you can't get the 1/4 divider until you pick the 133:133:33 setting. If you go lower, you have to pick 133:100:33 which sets the divider at 1/3.
Here's one vote that isn't for the CUSL2...
I've only had bad experiances with them. My Celeron 633 that makes 1070 on my EPoX i440 BX board only gets 1010 on the CUSL2.
I've had my IBM HDD at 45 MHz PCI bus, most components can handle 40 MHz PCI bus atleast. You will get the odd hard drive that can't, like certain Quantam or Maxtor drives.

Wait for the new ASUS TUSL2-C...It already has the new B-step i815ep chipset which will enable it to run both the Cumine and the Tualatin...Too late in the day to buy a non-Tualatin compatible mobo...At least you have a definite CPU upgrade path...

"Why can't we all just get along??"
Another vote for the Asus CUSL2. Spring the extra 15 bucks for the Black Pearl and you'll get it in shiny black with a nice screwdriver tool and the ability to upload .bmps to your BIOS (Looks great with a V8200 on it too.)
I should warn you to not expect to get more than 1200 mhz out of any PIII though - and that's with nutty cooling. Around 1100mhz shounld't be too much trouble. You might want to wait for a Tualatin mobo. The new PIIIs are expected to clock much further than than the coppermine.
