If it means anything, I updated to -current as of last night and I get

stall to 7 kB/sec upload from my G4 (OS X.4.5) to the G3 with bm0
1.07 MB/sec download from the G3 to the G4.

but, I was able to download at 56 kB/sec from the NetBSD ftp site  
without stalling using the -current generic_md install kernel. What  
would be different about the local machine initiating ftp and a  
remote user initiating ftp? I hope this doesn't indicate more  
interrupt problems :(
