Oh, that must have been fun to track down :-)

Yes, I checked the power and reset GPIOs and everything there looks
good. When you run stable-tracking, does WLAN work, i.e., does it
show up in "iwconfig" ?

By the way, with gta02-moredrivers-defconfig, stable-tracking now
builds to 2.21MB, i.e., much larger than what u-boot loads with
the default environment.

The following commands raise the limit to 3MB:

setenv bootcmd setenv bootargs \${bootargs_base} \${mtdparts}\; nand read.e 0x32000000 kernel 0x300000\; bootm 0x32000000
saveenv

Hmm, my wild guess would be that the introduction of read_subpage in
the NAND layer somehow caused this. The subpage logic isn't new per
se, and the NAND structure detected is the same as in 2.6.24, so it
must be something a little more subtle ...
