First of all thanks for your report.
You didn't send the exact error mesage.
I'm able to reproduce the following in 2.6.10-rc3-mm1:

<-- snip -->

...
LD .tmp_vmlinux1
drivers/built-in.o(.init.text+0x6464b): In function `init_scx200_docflash':
: undefined reference to `add_mtd_partitions'
drivers/built-in.o(.init.text+0x66ab8): In function `ns_init_module':
: undefined reference to `add_mtd_partitions'
drivers/built-in.o(.exit.text+0x8bf4): In function `cleanup_scx200_docflash':
: undefined reference to `del_mtd_partitions'
make: *** [.tmp_vmlinux1] Error 1

<-- snip -->

The patch below fixes them.

Please tell whether this fixes the problems you observed.
