I strongly suspect there's something wrong in the 604 code. 
- the mc problem seems to bite only people with 604s ( without your changes at least )
- the hangup at boot time when banging the keyboard helps - seems to happen only on 604s

There are probably other things and the set of known occurrences is way too small to allow any statistical analysis, but it certainly looks like that. I wouldn't be surprised if a -current kernel would just work on Brians machine but hang on yours, Riccardos, Johns... anything with one or more 604s.

btw. the current stuff works on my iBook, just as expected. 

have fun
Michael
