I have one computer that has had difficulties with udev since it was introduced.. (but much less so with the 2010 PCLinuxOS release). I think it just has difficulty with some hardware... the trick for me is getting it to a full boot once or twice and then it seems to work fine.
If you are getting far enough through the boot process to have video crashing, then you may be able to get through to a working desktop after a few clean, non-forced reboots.
Try adding
"splash=silent" "
splash=verbose" followed by a space and the number
3 to the end of your grub boot menu options so that the boot process ends at init level 3 (no graphics / desktop). You will most likely still see alot of output from udev, but eventually (..for me sometimes
up to 5-10 minutes) you should get a text log-in prompt.
At this point log in as root, and issue the command "init 6". this will cause your machine to gracefully restart. when it does repeat the process, and after the second init 6 reboot just let if boot normally (sometimes i get a disk check forced on first reboot, but the third
clean restart (..no reset buttons!) usually results in a good full clean OS boot.
..also, if you are not sure how to verify the MD5 on your disk don't hesitate to ask. If the problem is corrupted install media then no amount of restarting will help!
