I am running Debian Squeeze on an old Dell Dimension 8300 box. It has an AGP Radeon HD 4650 card. I use this machine to mine bitcoins, and today I noticed that the machine had rebooted! My precious uptime!
Anyway, my miner wouldn't start, so I figured might as well update my graphics driver, maybe that would fix the issue. I went to amd.com and downloaded the newest driver (12.6 legacy), but after installing it, aticonfig gave an error:
aticonfig: No supported adapters detected
I uninstalled the driver and figured I'd try to install it from apt. AMD has dropped support for the HD 4000 series in fglrx, forcing me to use fglrx-legacy-driver (currently only in experimental). In order to install this, I had to update libc6 (and some other important packages, like gcc), I had to use their wheezy versions. I finally got fglrx-legacy-driver installed, but I still got:
aticonfig: No supported adapters detected
Why isn't the driver finding my video card? I have a hunch it has something to do with the fact that it's an AGP video card.
Here is the output of lspci -v (why does it say Kernel driver in use: fglrx_pci?):

EDIT: fglrx 12.4 seems to work. Thing is, since I am on kernel 3.2, I need to apply this patch to common/lib/modules/fglrx/build_mod/firegl_public.c. I thought ATI dropped support for the 4xxx series after 12.4. Why doesn't 12.6 legacy work?
