It wouldn't work at all without the microcode. I'd copied it already
into the appropriate /lib/modules/*/ dir. Curiously the Debian kernels
can find the firmware there, but can't automatically load the drm2.ko
dependency from there.
The slowness went away when I compiled without debugging options.

Yes this works fine too, thanks!
I reverted to unpatched libdrm2/2.4.49-2, and so on boot when lightdm
started, Xorg detects no modesetting and it falls back automatically to
the vesa driver. (Seemed quite fast and usable, actually).
If I quit Xorg and manually kldload drm2 and radeonkms, the displays
go blank, but I can (blindly) restart Xorg, it detects KMS, and uses
the radeonkms driver giving accelerated graphics.
This is exactly the kind of fallback we want. It would be ideal though
if the radeonkms module could be auto-loaded (and its prerequisite drm2)
just as Xorg is starting up.
