Questions: New VCPI default is 256 MB, what was the previous

There wasn't one. It was set to 4G, i.e. the maximum anything could have
anyway.
Can I assume that non-dumb DOS extenders alloc their
memory through XMS rather than VCPI anyway, so most DOS extenders
Non-dumb DOS extenders allocate through both VCPI and XMS, as
available. Or they can pick the largest of one or the other, if they
must. What they can't do is bomb out with an incorrect error message when
one of those values is too large and leave the memory still allocated and
unavailable after exit, as your favorite DOS extender does.
MAX setting is? And: Do you mean 22 bytes of EMM386 local stack
or do you mean 22 bytes of DOS stack? I assume local stack, so
I mean 22 extra bytes of whatever stack is there when DOS calls into entry
of a device driver. If DOS can't spare 22 more bytes of stack for a
one-time call at startup, it has probably cut its stack reserve too low.
