I didn't see anything here, but on looking at the ChangeLog for rc1, I see a 
lot of stuff fiddling with firmware.  On my phenom x4, I get this very early in 
the boot:
[    0.558368] Unpacking initramfs...
[    0.648644] Freeing initrd memory: 3431k freed
[    0.651635] platform microcode: firmware: requesting amd-ucode/microcode_amd.bin
[   60.646738] microcode: failed to load file amd-ucode/microcode_amd.bin
[   60.646858] microcode: CPU0: patch_level=0x1000065
[   60.646977] microcode: CPU1: patch_level=0x1000065
[   60.647099] microcode: CPU2: patch_level=0x1000065
[   60.647218] microcode: CPU3: patch_level=0x1000065

Note the time, it kills quite close to a whole minute there, which at first 
would appear to be because there is not yet a mounted /lib filesystem to suck
it from.  I didn't build an rc1, but rc2 also suffers from this. 2.6.32.2 does
not do this although its firmware request takes place at the same point.
So it doesn't look like it is the lack of a mounted filesystem after all.

FWIW, because it was a hot reboot, the patch_level reported is the correct
level.

I am also seeing some complaints about my Audigy2 sound card, but what I saw
during the boot, never made it to the messages log.  Something about guessing
at the proper config, but I did hear kde sign on when x started.

Thanks Linus.
