Thanks, I notice in 2.6.23-rc3 there no longer are a series of

Thanks for pointing that out! 18.104.22.168 has 35 as the interrupt, while
2.6.23-rc3 has 5. 35 didn't make any sense to me since the old ppc
arch used 5.

Why <1d 2 1e 2 22 2> ? I can't seem to parse these numbers - how do I
know what to use for my external interupts 1,2 for phy's 0,1 using a
88E1121R and for external interupts 3,4 for phy's 2,3 using a 88E1111
