Welcome back!
Indeed, it turned out to be hard to drown in the Dead see. :-)
I will address all of your points except for followings.

+ if (xcount == 0x0000) {
Hm, I'm not sure this is necessary here... although I didn't see an
explicit mention that zero count means 64 KB in the datasheet -- which
it must mean if the BMIDE spec. was followed).
In ide-dma.c this check was added because of CS5530's brain damage...
Hmm, if I could test this case easily I will drop this. Otherwise I
will keep it as is for future investigation.
OK.

Parens around & and | are hardly needed...
You mean more parens are needed?
I mean less. :-)
