Does the R600+ driver perhaps load firmware only at open time?
They look the same in dmesg:
[ 1.648745] [drm] Initialized drm 1.1.0 20060810 [ 1.648824] [drm] radeon kernel modesetting enabled. ... [ 1.658077] [drm] Loading RS780 Microcode ... [ 1.733643] fbcon: radeondrmfb (fb0) is primary device ... [ 1.754301] [drm] Initialized radeon 2.11.0 20080528 for 0000:01:05.0 on minor 0
vs
[ 1.034278] [drm] Initialized drm 1.1.0 20060810 [ 1.034359] [drm] radeon kernel modesetting enabled. ... [ 1.038968] [drm] Loading R100 Microcode ... [ 1.238337] fbcon: radeondrmfb (fb0) is primary device ... [ 1.694374] [drm] Initialized radeon 2.11.0 20080528 for 0000:01:00.0 on minor 0
my syslog for the earlier boot has already rotated out, but from memory it looks the same as the previous boot.
