No. Though I'd advise everyone to stick with 33MHz PCI when they can
because it is safe. But even the VIA specs mention 25, 37.5 and 41.5 PCI

If you set a MVP3 or MVP4 chipset to 83 MHz FSB, you'll get 41.5 MHz
or 27.6 MHz PCI. And there are chips speced for 75 and 83 MHz FSB's -
Cyrix 6x86MX etc.

No way to get 33 here, if you *don't* want to over/under-clock the CPU.
