I've also not come across a case yet where drivers cannot be found at all for a device for Windows 7, no matter whether 32- or 64-bit. The problem if it exists is normally with the enabling software for these OEM's, like a fingerprint reader or cam full software but not the driver which given them basic functionality. There are workarounds for these software reinstalls in the brand notes at the end of Clean Reinstall - Factory OEM Windows 7.
