For those who have noticed, Sonnet has a new line of 68k upgrade cards 
coming out soon.  These cards are intended to be used to upgrade old '030 
macs by putting an '040 into the NuBus or PDS slot.  The cards come in 
both 68lc040 and 68rc040 versions with 32Meg of onboard RAM and an 
ethernet controller. The price ranges from $100 to $400 depending on the 
system.

They have no idea if these cards will work with NetBSD, but I've made 
arrangments to obtain one for testing.  They tell me to expect something 
next month.  If anyone is interested in the outcome, I'll post the 
results.  They will also post them on their Web page.
