I have compiled 2.6.28-20100903+0m5 (PR1.2?) kernel, modules and flasher.

The iphb patch applied as is, minstrel patch didn't. There seems to have been quite many changes in the minstrel module but the particular issue fixed by the old patch may not have been fixed (basically it leads to reboots with certain other chipsets [commonly found in mac laptops] connecting to the ad-hoc network, so it's quite easy to test...).

I have not yet tested these though they should work fine with rest of the firmware being still PR1.1. (For certain values of fine; for example the minstrel module might need a revised patch...)
