OK, works with that patch applied.

Yes it's the same with and without the patches:

# cat /proc/cpuinfo 
processor       : 0
model name      : ARMv6-compatible processor rev 2 (v6l)
Features        : swp half thumb fastmult vfp edsp java 
CPU implementer : 0x41
CPU architecture: 6TEJ
CPU variant     : 0x0
CPU part        : 0xb36
CPU revision    : 2

Hardware        : Generic OMAP2430 (Flattened Device Tree)
Revision        : 0000
Serial          : 0000000000000000

And omap2's have this in the revision registers for reference:

CPU: ARMv6-compatible processor [4107b362] revision 2 (ARMv6TEJ), cr=00c5387d

Tony
