Yes, there are problems with highmem on hypersparcs.

With ext3 root and ext3 as a module in the initrd and 3x64MB:
  banks 0,1,2 - boots ok
  banks 0,5,6 - failed to mount root (tested both 2.6.11 and 2.6.12)
error message was "mount: error 15 mounting ext3"

I also tested the latest Aurora corona kernel (2.6.11-1.1166sp1) and it 
mounted root without problems.

And I tried appending "memdM", but it crashed before initializing the 
console (-p showed an endless loop of errors).

Hope that helps,
Bob
