S3C6400 SMDK6400 HSMMC problem

Hello,
First: i'm new to this list. The new listinfo page tells nothing
about attachments (are they allowed, size?) or where to put them
now - so for now i don't attach two files i actually wanted to
provide (my adaptions for u-boot-hsmmc, kernel .config).
Now the problem:
i'm trying to get linux-2.6.32-rc5 working on a Samsung/Meritech
SMDK6400, (Processor S3C6400.)
The kernel is load sucessfully using u-boot-2009.08-rc3 from the
DOS-Partition of a SD Card via the S3C6400 HSMMC 0.
Note1: to get this working I adapted src/cpu/s3c6410/hs_mmc.c
from OpenMoko / qi for u-boot.
However the kernel's sdhci driver has problems (I/O errors) using the same
S3C6400 HSMMC 0 (see below) when trying to mount the root partition from
the SD Card.
Besides some additional printk statements in the kernel source, the
only relevant modification (to use HSMMC0 instead of 1) was using
s3c_device_hsmmc0 instead of s3c_device_hsmmc1 in
static struct platform_device *smdk6400_devices[] __initdata
file: arch/arm/mach-s3c6400/mach-smdk6400.c
Any hints where to look next are highly appreciated.
Best Regards,
Markus Schwarzenberg
