Darn it. I get the same kernel panic with that one.

I'm compiling locally but I don't expect that to make any difference. 
I'll need to go pawing through the release notes and see if there are

(Just before it enumerates vgapci0)

but I can't be sure because the screen moves so fast that even slow-mo 
video is just a blur.

I am running 11.2 on SunFire X2100 M2 but according to your dmesg it 
uses different chips. X2100 M2 has nVidia nForce MCP55 chipset for ATA 
devices, nfe for 2 NICs and Broadcom bge for the other 2 NIC's.

Did you tried to boot "safe mode"? (selectable in boot menu).
Or you can try to disable / enable some settings in the BIOS. Something 
related to USB or onboard VGA etc. may help.
