It's funny, I tried the same yesterday, with the next-samsung-6410
kernel and run into the same error message.
On the mailing list I found the patch "[PATCH 3/6] S3C64XX SPI: Header
for passing platform data" from 21th November 2009, which I tried.
This seems to work. Then I tried to apply the patch "[PATCH 6/6]
SMDK6410 SPI: Added spidev support as an example" to get the SPI
driver initialized on the SMDK6410 board. But this leads to other
compile errors:
linux-2.6-samsung/arch/arm/mach-s3c6410/mach-smdk6410.c:484: undefined reference to `s3c64xx_spi_set_info'
arch/arm/mach-s3c6410/built-in.o:(.init.data+0x90): undefined reference to `s3c64xx_device_spi0'
make: *** [.tmp_vmlinux1] Error 1
And once dev-spi.c is compiled into the kernel - to resolve the
undefined reference error - the kernel crashes during bootup
(<4>SLUB: Unable to allocate memory on node -1 ...). After this
I gave up.

What do you mean with 'unmodified kernel'? Where can I find the
latest Kernel with S3C6410 support?
