If you would like to confirm if udev did get upgraded, You can  
boot from CD, enter chroot (refer to the gentoo handbook,
just don't do the fdisk or formats ;-) and emerge genlop. This is a
great tool that reports on the emerge activity. From there you can type
"genlop -l" and is will show you all the packages emerged and when. 

If you feel (or confirm) that the problem is related to udev, you may
want to back down to the previous version you had installed. Hopefully
it's still in the tree. If it's not, this is a good time to add the the
--buildpkg option to EMERGE_DEFAULT_OPTS in /etc/make.conf, that way you
will have binary packages for each package you emerge going forward, and
can easily revert in case of emergency.

Can you see the other partitions when booting off the CD? Before you
enter the chroot environment above, make sure you mount all your
partitions as you did during the install. Hopefully you can see the data
and the other partitions. If not it sounds like you have may have some
drive corruption.

Good luck!
