Does your kernel have YAFFS2 support (you need to patch it unless TS has
already done that), and is it enabled? NAND support works fine here in
2.6 with both the 32MB and the 128MB 7260.
Also, if you have the 128MB version, you might need a patch for the
partition table. It's needed for vanilla kernels, I don't know if the TS
2.6 tree has the same autodetection as 2.4.
IIRC I got it from this list, but I can't find it right now, so here it is:
