I've tried to test 2.5.42-mm2 but it doesn't compile. There were (I
assume 'sard') changes made to remove the DK_MAX_MAJOR etc. but there is
to patch to drivers/md/md.c so it fails to compile:

# find -name \*.c | xargs grep DK_MAX_MAJOR
./drivers/md/md.c:static unsigned int sync_io[DK_MAX_MAJOR][DK_MAX_DISK];
./drivers/md/md.c: if ((index >= DK_MAX_DISK) || (major >=
DK_MAX_MAJOR))
./drivers/md/md.c: if ((idx >= DK_MAX_DISK) || (major >=
DK_MAX_MAJOR))
