Did you actually try this patch against a vanilla 2.6.19 + 2.6.19-at91.patch.gz?

a) it does not apply cleanly. failing in
   arch/arm/mach-at91rm9200/at91rm9200.c	and
   include/asm-arm/arch-at91rm9200/hardware.h

b) asm/arch/at91rm9200_tc.h is called asm/arch/at91_tc.h now

c) Kernel with adoes-ipipe compiles (after fixing the above), but xenomai
does not compile and bails out with
