Description of problem:

After booting from todays rawhide boot.iso, each keypress, (a-z, backspace,
enter, fN keys) registered in a double press. This was only applicable to linux,
as it worked fine in the syslinux boot loader.

Seemed to behave this way in the terminals, not just anaconda.  This may not be
the correct place to assign it, but I figured it is the place to start as kernel
parameters fixed it.

Version-Release number of selected component (if applicable):
kernel 2.6.17-1.2505.fc6


How reproducible:
Every time.

Steps to Reproduce:
1. Boot from todays rawhide boot.iso
2. at the boot prompt enter: linux text
3. Wait for anaconda to start
  
Actual results:

Anaconda starts, and every key press is registered twice.

Expected results:

Computer to accept a single keypress, as a .. single keypress.

Additional info:

Workaround is to boot with acpi=force noirqpoll
