For those used to seeing me every day on Galt's CTF: Apparently I had not one but two dead network cards; the one I was using when the problems started, and the one I switched to because I thought it was fine - until I discovered otherwise after fighting with my 'puter for a couple days. Suffice it to say, if you ever see tulip_stop_rxtx() failed (CSR5 0xfc664010 CSR6 0xff972117) in dmesg, just huck the card in the trash and get a new one.
Anywho, I have played some offline today to verify the GPU is in good shape (I modded the firmware on it a while back to get a bit more out of it), I'm not seeing any other errors with xorg or kernel borks or resource allocation failure on the pci bus, so I'm calling this resolved when I get off my bum and go get a shiny new NIC to stick in the box.
Fingers crossed, cyall tonight!
Hugs and kisses,
