Oops!  My fault.  I was composing my reply a bit at a time, adding
stuff with each reboot, and couldn't see my inbox had this followup
from you before I hit Send.

ACK.

Personally, if I had champagne here, I'd have popped the cork already.
This is the first 2.6.2[67] kernel I've had that can boot without
"hpet=ignore" or reverting the 2 commits from February.

Here are the messages about ignoring conflicts.  The full 'dmesg' output
is attached -- gzip'ed because it was over 100K (I used kernel parameters
"debug initcall_debug", and a bunch of unexpected stack traces also
appeared).
