Right now I'm working on a U-BOOT driver from scratch for a S3C2410
board.  The S3C2410 has hardware support for 4 bit SDIO, the drivers I
have seen have to much extra stuff to make for clean reading so I decided
to start my own.  The PXA255 driver I'll probably patch to at least support
SD memory detection.  I have been working at most 2hrs per day at this so
the PXA stuff is probably several weeks away.
As for help, you have alreay provided a nice toolchain and distribution I
can't thank you enough.
