[sp] If you noticed, earlier u-boot version was identifying your board as:

U-Boot 2009.11 (Oct 30 2010 - 13:14:45)

OMAP34xx/35xx-GP ES1.0, CPU-OPP2 L3-165MHz
OMAP3 EVM board + LPDDR/NAND

Now,

U-Boot 2010.09 (Nov 07 2010 - 07:08:44)

OMAP3630/3730-GP ES1.0, CPU-OPP2, L3-165MHz, Max CPU Clock 1 Ghz
OMAP3 EVM board + LPDDR/NAND

That's ai improvement.

However, in your log, I see folloing:

[ 0.000000] Total of 96 interrupts on 1 active controller
[ 0.000000] Could not get gpios_ick
[ 0.000000] Could not get gpios_fck

Looks like there are some changes - either in your Kconfig or
elsewhere in the code that "get" gpio clocks is failing.

The SMSC chip is "virtually" non-existent for the Linux kernel
here onwards.

My kernel version is "Linux-2.6.36-rc8-09072-g661df74-"

I have not yet looked at, but there is possible "break" on on mainline for EVM due to gpio related changes.
You could be experiencing this break...
