Today's Update causes boot freeze at: "Checking for hardware changes"

["Daniel B. Thurman" <dant cdkkt com>]

Folks,

Is there something I can do to revert back to a previous install
via rescue disk & yum to bypass the hardware-check hang issue?
If there is a yum package what is it called?  Or is it perhaps easier
to edit one of the rc scripts to bypass the hardware-check process
until this issue gets fixed?  If so, is it kudzu or what?

Thanks!
Dan
