I can confirm that the oops seems very much related to when udev is
loaded in the initrd.
This was noted in the changelog on Dec 19:
a/udev-165-i486-1.txz
I am going to test rolling back to udev-164, if I can find it in my
repository.

I rolled back to the last version I could find, udev-164-i486-3.
So far, it is working fine. That gives some circumstantial confirmation
that it is udev that is at fault, and not mdadm, lvm2, or another package
of the set of updates issued on the same time interval.

Did you notice 2.6.35.10 in it's new home on kernel.org?
I'm no help with udev...
Grant.
Here I have the latest with version number 4, in case someone needs it:
