Sorry... On a reread of the original post I notice
you did say you could login remotely when it
froze, so this certainly is not the ndiswrapper bug.
I believe it is video related. What type of video card is it?
Some have problems with the vt switching you are
doing - you might find googling about that specific
issue: freeze and the video chip or module name,
will help. Checking the X log might give a clue
depending on the type of X window you are running.
If you have any bootable CDs around, like KNOPPIX,
it is a quick way to give the system a test drive
with an alternate set of kernel modules, etc.
