CCing Tom Bylander as he sent me a mail off-list saying he experiences a similar issue on an FX 5200. Tom, maybe you'll have better luck bisecting this than I did?

OK, so this is still reproducible on Linux 3.4-rc1+ (Linus' master). I captured the dmesg output before (3.2.13, which is a working kernel), and after (3.3.1 and 3.4-rc1-00144-g01627d9 - both fail in an identical manner). All three logs are attached in full (gzipped). One thing that immediately jumps out is the WARNING in the 3.4-rc1+ log that occurs early and did not appear in either of the other logs: ------------[ cut here ]------------ WARNING: at /home/nick/misc/linux-2.6/arch/x86/pci/i386.c:60 pcibios_fwaddrmap_lookup+0x1d/0x3d() Hardware name: K8N-E-Deluxe Modules linked in: Pid: 1, comm: swapper Not tainted 3.4.0-rc1-00144-g01627d9 #47 Call Trace: [<ffffffff81026baf>] warn_slowpath_common+0x80/0x98 [<ffffffff81026bdc>] warn_slowpath_null+0x15/0x17 [<ffffffff8129f79f>] pcibios_fwaddrmap_lookup+0x1d/0x3d [<ffffffff81687306>] pcibios_allocate_resources+0xd4/0x217 [<ffffffff81688447>] ? pci_legacy_init+0x3e/0x3e [<ffffffff81687460>] pcibios_resource_survey+0x17/0x2d [<ffffffff81688dfd>] pcibios_init+0x28/0x3a [<ffffffff8168848e>] pci_subsys_init+0x47/0x4d [<ffffffff810002e2>] do_one_initcall+0x78/0x126 [<ffffffff81662bab>] kernel_init+0xe9/0x17a [<ffffffff8166248a>] ? rdinit_setup+0x28/0x28 [<ffffffff8131ac44>] kernel_thread_helper+0x4/0x10 [<ffffffff81662ac2>] ? start_kernel+0x321/0x321 [<ffffffff8131ac40>] ? gs_change+0xb/0xb ---[ end trace 4eaa2a86a8e2da22 ]--- Other than that, I diffed the 3.2.13 log and 3.4-rc1+ log and grepped for nouveau-related differences.
