without DMA (which is not optimal for my needs) and SD doesnt work at
all atm. All the other devices should work (network, usb does for sure)...

No, I have not done this, but the sequence to bring HRT to 2.6.21-TS
would be (about):
* Download
http://www.kernel.org/pub/linux/kernel/projects/rt/older/patch-2.6.21.6-rt21
* Apply that patch to 2.6.21-TS sources, fix any conflicts / rejects.
* That patch above adds HRT to ep93xx. Find the ep93xx specific bits,
and then patch the marvel orion in a similar way. As a guide to what
is needed, you could look at the later patch (2.6.27?) that brings HRT
to the orion chip. Also, you could look at:
http://www.kernel.org/pub/linux/kernel/projects/rt/older/patch-2.6.22.1-rt9-broken-out.tar.bz2
which is the earliest -rt version to break out patches separately.
That would help picking the bits that are ep93xx specific, and later
broken out versions would help you find what is orion specific.
Obviously this could be a big time sink. It may be better to spend
effort to help fix the problems of mainline 2.6.28 on TS-7800. It is
unfortunate that TS locked on an early kernel version, before the
orion stuff was included in vanilla kernels.
