This bug was fixed in the package u-boot-linaro - 2011.09.6-0ubuntu1

u-boot-linaro (2011.09.6-0ubuntu1) oneiric; urgency=low
* omap4: reduce default operating point for 4460 devices
Reduce the operating point for 4460 to OPP100 (MPU at 700MHz)
(LP: #867670)
From bug report:
With both A9 cores loaded 4460 reaches max temperature in about 30s at
the
current operating point of 930MHz. The operating point should be
lowered to
700MHz.
It appears the panda heats more than I thought (and much more that the
blaze),
and by loading the 2 cores I can quite easily reach max temperature at
920MHz
(it takes around 30s on my board!).
At 700MHz, the temperature still increases but much slower. So if the
A9 cores
do not run at 100% all the time we shall be ok.
So for now, we definitely need this change if we don't want to run with
a
heatsink...
* mmc: omap: enable high capacity
Enable high capacity to host capability.
Fixes eMMC detection on boot from MMC/SD card.
mmc: omap: config VMMC, MMC1_PBIAS
Config VMMC voltage to 3V for MMC/SD card slot
and PBIAS settings needed for OMAP4
