But we know, that 3780i (which is supported) never uses them, and
this knowledge is expressed by testing iobase & 0xF00F == 0 in
tp3780i.c code,  and
chip which is used in older thinkpads uses only them.

BTW, Crystal Sound 4280 on Thinkpad 755cs uses same addresses, but has
nothing to do with MWave.

Nothing new on this page since I've looked at it year ago.
