Sure, but what's the point of using bank switching?  First of all,
rather few of the installed base of GS's have more than 1.5 or 2 megs
of RAM; we're not even pushing the 8 Meg barrier yet so why worry
about more.  Second, bank switching would slow the machine down
further and it's not fast enough as is.  Yup, we could probably come
up with a really nifty bank-switching scheme, but we don't need to yet
so we won't.
