x86: Dell Precision WorkStation 690 reboot quirk

This Dell workstation gets stuck on reboot unless booted with
the paremeter reboot=bios.

This patch has been submitted 3 times already to X86 ARCHITECTURE
maintainers w/o any feedback so far. Trying my chance on the LKML.

Patch is against 2.6.36.1
