Oliver,

yep, it's some kind of a progress now. Freeze moved to pmap_bootstrap() 
at arm/arm/pmap.c:2507. At the moment I try to understand the code around.

Thanks for your patches but it seems I was wrong about `definite 
compatibility' of the sa1110's uart and the 8250. After carefully 
reading datasheets I found these chips are thoroughly different. Sorry 
for my inattention.

Regards, Mikhael
