David,
I tried to boot my E250 (2x400MHz, 2GB) with 2.6.18-rc1 and your
latest patches, without success.
It crashes while probing the PSYCHO PCI controller:

Quick investigation shows that pbm->name is used a tad too early in
pbm_register_toplevel_resources. The included patchlet fixes that,
allowing the boot to go a little further, but not much :

Looks like no IRQ can be requested, probably a problem with the new
IRQ framework.

[SPARC64] Fix PSYCHO PCI controler init.
pbm->name should be initialized before calling
pbm_register_toplevel_resources. Move the call a few lines down to
avoid a nice Oops.
