Christoph,

I understand all that, my comment was worded wrong I guess.  What we
need is a build of the restricted drivers package for the -server
kernel.  There appears to be one for all others.  Yes they do have
packages for the individual drivers but you have to use module-assistant
and have the module source package to build them.  The nvidia-glx-*
packages are just the userspace libraries I believe.  Also there is no
madwifi  module-assistant compatible package and the atk5k driver
doesn't support my card (Fedora includes 2.6.23, maybe 2.6.24 is
better).  I see a couple of solutions:

1. Enable the HIGHMEM_64G option in -generic.
2. Build restricted drivers for -server.
3. Build a special -pae kernel if systems with low memory or older CPUs for problems with PAE support for some reason (Fedora does this).
4. You can of course run 64-bit but there are still a few issues in terms of compatibility and also lesser common 32-bit libraries are not available.

I think #1 would be best, #3 would be a lot of work, and #4 is a
workaround.

Not rambling just observations.

-Eric
