Andy,

OK, go ahead and point us to the source for libext2.  We'll take a shot
at this starting early next week after finishing up some other stuff,
but we may need some help.  After talking with Rick this morning, it
turns out that Max did the PROM support for the current fs support. =20

Even after your smart-ass remark about how I don't know how to hook up
interrupts, we're still here to help!  :-) =20
