MassMhz is right. 37Mhz PCI bus is pretty OK with most PCI bus. There were some Maxtor drives as well as some SCSI cards not running well at that speed in the past, but it should be OK with most of the today's hardware.
Cyrix had some chips officially running on 75Mhz bus (or 37.5Mhz PCI bus) ie. MII333. Therefore, I would not be too worried if I were you.
