There was a shift in certain flags in the Linux kernel starting at ver
2.6.19 that can give problems for people trying to compile external
modules against it. The ipw3945 kernel module in the experimental
repository will compile fine against the 22.214.171.124 (works very well, too)

Mainly, it's a method to maintain backwards compatibility with various
peripheral manufacturers - can't expect everybody to retool at the drop
of a hat, so to speak. You'll notice on your machine that various parts
of it DO have 64 bit width memory addressing available, and this can be
utilized with the kernel option I pointed out yesterday. Bus bandwidth
remains at 32 bit for the moment. This is IMHO the genius of the dual
core processors. We have a radical perfomance enhancement without
having to open up the entire bus, which is much more expensive,
physically. Run lspci and you'll see what I mean.
How about graphics and sound? OK?
