can you send me your config? or better yet, your diff, which I will commit and then start testing.
I just this morning got the ARIMA HDAMA working with a bproc phase 1 boot, it was a bit of hackery needed with the kernel to tell it what kind of irq router it had.
I wonder how the normal bios handles the PIRQ? getpir returns one that is clearly bogus. I guess linux never tries to use it? But a lilo boot of phase 1 reveals that it does find some sort of pirq table, and does something I can't figure out ... oh well that's for later.
