I have gone back through the process and can confirm that on ESX 4.1 the 2.6.32-25-generic kernel segfaults during boot, the -pae kernel does not segfault. The udevadm command segfaults:
udevadm[94]: segfault at 1 ip 00000001 sp bfb55514 error 4 in libdl.so.2
After the segfault, the user is placed in the initramfs console. Running udevadm a number of times on this console it segfaults about 50% of the time.
