fglrx on AMD64 Karmic works (partly) for me, with a 4670 desktop card.
I don't see any kernel crashes or boot problems.  OTOH, I boot up in
text mode with no splash-screen crap of any kind, so when I run startx,
it's from VGA text mode, and the video card wasn't in any other mode
from POST until then.  (text grub, and no splash boot for the kernel
either.  console-setup or something loads a new VGA font, but that's
all.)  So perhaps the crashes you're seeing are because the card is in a
different state from mine when the module loads?

 Wait, you said it hangs right after _loading_ grub?  Before it boots
the Linux kernel?  So you can't interrupt GRUB's auto-boot timeout and
get to its command prompt?  That sucks!  And maybe I should open a new
bug.  Ubuntu maintainers, please advise.


The reason I say only partially working for me is that there seems to be an ABI problem with 64bit opengl.

every visual has the same garbage numbers.  So probably in 64 bit mode,
the OpenGL library is looking at the wrong block of memory when looking
for the supported visuals from the server, so nothing works.  32bit
games work fine, with no performance problems or anything  (e.g. I
played a bit of nexuiz, and that uses lots of recent OpenGL features.)
Linux Descent3 also runs fine.  (runs quite well on a c2d + 4670,
actually :)

  Xv works, for amd64 and i386 binaries.  I haven't noticed any problems
on my desktop, running fluxbox, gnome-terminal and firefox, and
sometimes other GUI stuff.

 Any 64bit binary that wants to use OpenGL gets the same error about not being able to find a visual.  Even glxinfo (unlike fglrxinfo) bails after that:
$ glxinfo -v
name of display: :0.0
Error: couldn't find RGB GLX visual or fbconfig


 same situation with fglrx from Karmic
ii  fglrx-kernel-source        2:8.660-0ubuntu4           Kernel module source for the ATI graphics accelerators
or ATI Catalyst 9.10 (8.661)

 I'm running Ubuntu's 2.6.31-14.48-generic kernel.

my xorg.conf was generated from empty by aticonfig, and has nothing
special.  I moved aside my old one that's been growing cruft for
years...  (but worked with Jaunty & Catalyst 9.8).

 I've googled, but I haven't seen anyone say anything about the problem
I'm seeing (everything works except 64bit opengl).  That's weird,
because I'm using the Ubuntu versions of everything.  Although I don't
have ubuntu-desktop installed;  I prefer a lighter-weight environment...
