Yes, it is stable, with a couple of well-known problems.

ATA: OK as long as you don't enable DMA writes (*)
DDR: OK (use icecube_5200_DDR configuration in U-Boot); the LOWBOOT
option is not working yet (we are working on this)
I2S: simultaneous reading and writing is impossible (*)
AC97: ditto

BestComm CAPI which might become availabe by mid February.

Forget it. Why would you want to do that? Which features do you
expect from 2.6 which are not available in 2.4?

No comment.

Our current stuff is on our CVS server, in the linuxppc_2_4_devel
tree. As far as the 5200 is concerned this includes stuff that was
submitted but not yet added to the linux-2.4-mpc5xxx tree (but Tom
promised to add our patches).
Best regards,
