I'm surprised that a SONIC card is recognized, to tell you the truth.  The
problem is most likely that the ae driver is turning on interrupts, and
your Performa 550 has a video interrupt waiting to be serviced.  I've
recently committed code to handle the internal video interrupt on certain
machines (including, I think, yours).

While NFS won't work with -current kernels and 1.1 binaries, the following
kernel should otherwise do the job for you:

	ftp://ftp.plexus.com/pub/NetBSD/GENERIC-9.tar.gz

Note that this is _not_ an official kernel in any way, shape, or form.
Please do not advertise the kernel or the site you got it from to anybody
else, as I won't be able to offer this if things get out of hand.

Future "official" kernels should have this fix as well.
