Here's a photo of the screen once the booting froze:

I removed most of the non-working kernels 2.6.32-573-*, except for the 
latest one; here's /etc/grub.conf

I don?t know how you get ?probably? out of these two screenshots.  Both machines
seem to be crashing in about the same place in the boot, and both seem to have
Intel graphics, but the resulting crashes are quite different.

The test is simple, though: Max, try removing ?nomodeset? from one of the
failing kernel option lines and see what happens.
