Re: 2.6.20.7 locking up hard on boot

["Marcos Pinto" <markybob@gmail.com>]

It took me several hours, but I just got done combing things over with
bisect as Greg requested.  This is what git spit out as the problem
patch in the end:

7639e962234c76031d1ddf436def7fd9602be560 is first bad commit
commit 7639e962234c76031d1ddf436def7fd9602be560

   adjust legacy IDE resource setting (v2)

   adjust legacy IDE resource setting (v2)

   The change to force legacy mode IDE channels' resources to fixed non-zero
   values confuses (at least some versions of) X, because the values reported
   by the kernel and those readable from PCI config space aren't consistent
   anymore.  Therefore, this patch arranges for the respective BARs to also
   get updated if possible.

Please let me know if there's more that I can do.
Thank you,
