I've had this problem when using yaboot, but not BootX.
Apparantly, there's something beneficial that MacOS does to
initialize the PCI bus WRT the PCMCIA bridge that the 2.2.x
kernels do not do. However, there's something detrimental
MacOS does to the PCI bus WRT XFree86 4.x; hence, you can't use
kernel 2.2.x, PCMCIA, and XFree86 4.x all at the same time.
If you're using XFree83 3.3.6, then you can downgrade to BootX
and that might work. If not, you can try:
setpci -v -s 13 command=7 19.b=1 1a.b=4 1b.b=b0
after having booted using yaboot and see if things get better
for the Wavelan card. If not, I think your boot/kernel setup
simply leaves you SOL.
P.S.: I have a happily working Lombard running 2.2.17, BootX,
XFree86 3.3.6, Wavelan. I want to upgrade to XFree86 4.x, but,
to do that, I have to switch to yaboot (and not have a working
Wavelan card) or switch to kernel 2.4.x that, supposedly, does
better initialization of the PCI bus. Several months ago, I
tried this and the improperly initialzed PCI bus made XFree86
4.x unhappy that made the kernel crash and take out a few
blocks on my root partition right where glibc is rendering the
machine unbootable. After a few days of hair pulling just to
figure *that* out, I had to boot with a rescue image, mount the
root martition, and salvage the root partition via a cross-over
cable to another machine. I then had to reformat my root
partition and put stuff back including a fixed glibc.
Needless to say, I'm not really wanting to take a perfectly
working system and tweak it any time soon even if it means not
using XFree86 4.x. I might get up the courage and stamina to
try this again sometime once kernel 2.4.x settles down some
