Hey folks --

I've been having trouble with my firewire pccard.  Inserting it would 
cause my machine to hang (actually, it would sorta work, but the 
keyboard would die and wouldn't shut down properly and other strange 
things).  Anyway, my old IRQ settings (the PCI section of the BIOS 
config) were:

A  5
B  6
C  9
D 10
E 11
F  5
G  7
H  9

(I think i picked this arrangement up from one of the many 
linux-on-the-t40 documents floating around).  I then tried putting them 
all on autodetect, but it would still hang.  Then I just tried assigning 
them sequentially:

A  3
B  4
C  5
D  6
E  7
F  9
G 10
H 11

And this seems to work!  But is this ok?  I just assigned them 
arbitrarily, trying not to repeat any.  So is this ok?  Does anyone have 
a better working configuration?
