Badness in 2.6.15-rc1 on 8xx

[Joakim Tjernlund]

Anyone seen this when booting 2.6.15-rc1 on 8xx?
  Mount-cache hash table entries: 512
  Badness in dma_alloc_init at arch/ppc/kernel/dma-mapping.c:346

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.
