kernel-2.6.7-1.441 - x86-64 - difference between "quiet" and normal boot?

[Marshall Lewis <marshall novafoundry com>]

After installing kernel-2.6.7-1.441 on my opteron, I'm having an odd
boot problem.  If I boot up with the "quiet" kernel parameter, my boot
will hang when starting usb.  If I don't, it won't.. boots just fine. 
Any thoughts?

Also.. did something change with the keyboard handler? .. I have to
really type fast at the console now, there is almost no delay before it
starts repeating keys.
