Yes i know. Dosen't look like they are having problems with it in  
linux land, and aren't there driver in the tree that deal with bugs in  
some chip revisions?

After a quick look over at32ap700x and at91sam9261ek errata it dosen't  
look like there are any show stopper bugs for not using the same smc  
driver on both archs. Difference between them are:
at32ap700x has 6 chips selects while at91sam9261ek has 8
"Special" functions (CompactFlash, SmartMedia, NAND..) are set in  
different registers not belonging to SMC (same for both archs but  
different registers)
