Can you attach md module inside modules package?

are you sure it's available within 2.6.22 kernel?

It's module needed for mdadm to work (software raid).
It's available since 2.6.17 kernel.

This requires CONFIG_MD=y in kernel config. Probably, modules will not work 
with kernel from public available firmware images. So, rebuild of entire 
firmware is needed.

We can prepare custom build for specific router (You didn't provide such info), 
but raid support in 2.6.22 are very old and can contain some serious bugs.

Well, I just checked that full kernel rebuild is not needed. And you need 
MIPS32r1 modules.

At last, which kernel raid options (see list below) do you need?
CONFIG_MD_LINEAR
CONFIG_MD_RAID0
CONFIG_MD_RAID1
CONFIG_MD_RAID10
CONFIG_MD_RAID456

I just wanna say that it's working perfect.

Well, we will add this modules to public build. Probably, after adding some 
kernel.org upstream fixes.

If it is possible, please test raid repair procedures.

Partitions on mdX device are not working.
I can fdisk it but there is no md0p1, md0p2, etc files in /dev/.

I will try to test repair procedures later.

It is a problem in udev + userspace daemon (mdev), seems to be /etc/mdev.conf 
has to be modified. See line like:

md[0-9]*        0:0 660

Probably, you has to add following line to mdev.conf:

md[0-9]+p[0-9]+     0:0 660

It will be best, if you can find proper line for mdev.conf.

actually, mdX is already partitions
second - names could be either /dev/md_d0p1 or /dev/md/d0p1,
check DEVICE NAMES section and --auto options explanation in mdadm(8)

mdadm from http://lesiuk.net/files/asus-rt/ says:

mdadm: can't resolve symbol 'posix_memalign' in lib 'mdadm'.
or
mdadm: can't resolve symbol 'nftw64' in lib 'mdadm'.

I'm trying to crosscompile my own one but it's something that will take some 
days :(
