I built last week's stable-tracking, there are various issues with it
but it boots.  I had to do the following manually:

ln -s arch-s3c2410 include/asm-arm/arch

Normally this was done by Makefile, I don't yet know why that changed.
 Beside the mtdblock issues I see there's also a funny problem with
time running ~6x slower on my gta02.  I already checked that it's not
related to the dynticks patch.
