All of the RAIDframe code is 64-bit w.r.t. sector sizes.  I think 
there still may be a couple of 2^32 issues with respect to stripes,
but those are slowly getting fixed as well...

I believe so....  That is, the code is there, but I've not tested it 
myself...

This is the change that added the functionality:

http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/dev/raidframe/rf_netbsdkintf.c#rev1.213

so it should be in 4.x too.

Later...
