Kernel fixes

A few kernel bugs were fixed (a serious kernel stack corruption by a stray DMA was a fun one to track down).

The SD/SDHC/SDXC/MMC driver in the kernel now works very well, and integrated with the block device manager and the FS manager gladly mounts volumes on it.

Now back to working on RtLib

[also the GDB stub in kernel is almost complete, so debugging RtLib and user apps will be nice and easy]

Excelent news Dmitry!!!.. I'm allways eager to have news about this. Thanks!...

Speaking of SD driver, just curious about if the SD driver is a basic 1 to 4 MB SD size card or will it be able to work with SDHC cards as your PowerSDHC driver?..either way I'm very excited about DGOS, thanks a lot.

The driver in the kernel is the same codebase as PowerSDHC, so it supports: SD, miniSD, microSD, SDHC, miniSDHC, microSDHC, SDXC, miniSDXC, microSDXC, MMC, MMCplus, and RS-MMC.

WHOAH!!! Great external card support! This is the kind of thing we all wanted!
