Sure, but validating a 60Hz mode with a monitor capable of 75 at that
resolution shouldn't fail, unless you have really weird mode validation
semantics.  Or your mode validation relies on VBE, and throws 60Hz modes
away because they're not in the BIOS table, or something.

Daniel, wishing for the day i8xx didn't rely on VBE
