Yeah, my guess would be that you're using an nVidia card and didn't 
install the nvidia driver for your new kernel. Or something along those 
lines.

I'm guessing it was actually leaving you at a command-line login, which 
is something entirely different from single-user mode...

The second one is probably the one you were running while upgrading the 
kernel. You had to have a kernel installed on your machine already to 
be able to install another one via apt-get...[1]

Yes. The .at kernel has XFS and V4L2 support compiled in (among other 
things), the other one doesn't.

Native POSIX Thread Libs. Improved kernel threading found in the 
2.6-series kernel, back-ported (or maybe they just developed it, I'm 
not certain) by Red Hat into their 2.4 kernels. 2.4.22 is the base 
kernel version, the rest is revision-level info (1.2188) for Red Hat, 
the nptl addition to say "this is an NPTL kernel", and that would be it 
for a kernel straight from Red Hat. The _48 is the ATrpms revision 
level, the rhfc1 says "this kernel is compiled for Red Hat's Fedora 
Core 1", the at says the kernel is from ATrpms. Or something like that.

If my guess was correct, you need to install the nvidia-graphics kernel 
module.
