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
