So things are getting better on my Libretto L2. Christos found out
that the PCIBIOS IRQ table actually does exist, it just starts with
_PIR rather than $PIR. So I can boot ok with a PCIBIOS-enabled
kernel and most everything seems to work (including the sound card
and CARDBUS when I enable it).

However, the one thing that isn't working yet is USB. (Though this
does work with PCIBIOS disabled.) It seems that something is a bit
odd about the way it's being set up, comapred to other devices;
note the

    000:20:0 0x10b9 0x5237   A  0x06  10  2    WARNING: preserving irq 7

message below. (This is surely the USB controller, since it normally
uses IRQ 7 when PCIBIOS is not enabled.) In this configuration I
can plug stuff in, but the system never receives interrupts on IRQ
7.  So I added PCIBIOS_INTR_FIXUP_FORCE to my config file, which
changes the line below to

    000:20:0 0x10b9 0x5237   A  0x06  10  2    WARNING: overriding irq 7

When I boot and start X, I can plug in a USB mouse and it probes
and attaches wsmouse1. But again some weird interrupt thing seems
to happen; the mouse doesn't work, and vmstat indicates that I'm
not seeing nearly as many interrupts as I should be when I move
the mouse around. Normally several seconds of continuous mouse
movement will generate hundreds of interrupts; in this instance
over three seconds I saw three interrupts on IRQ 10, which I suspect
were all other devices (such as fxp0) on that IRQ anyway.

So I'm wondering where to go next with this? I don't really know
much about PIR setup, but I'm willing to try any ideas that anyone
has.

Note that this is all using stock kernel source as of a couple of
days ago.
