Anyone seen this when booting 2.6.15-rc1 on 8xx?

The kernel boots just fine into user space so it seems harmless, but I
suspect it will bite me later.
Something anoying:
Why did the new cpm_uart driver change major and minor number for the
tty?
As it is now I can't boot my 2.4 rootfs as init think it should find the
console on ttyS0.
Would be great if major and minor could be configurable.

I am currently working with 2.6.15-rc1 on MPC852 and I am seeing a similar
problem.

Have not had time to look at it yet, however I was not getting this on
2.6.11.
