Actually, most of the programs that won't allow a modification of
startup-sequence or startup from workbench are games (which I for one
would not want to have 32bit memory for, after all most of the arcade
games are fast enough without an accelerator...).  Also, Booting with
1.1 is not the best of solutions (as many programs require 1.2, and
there were a lot of things added from 1.1 to 1.2) and is usually a
pain (ie how many of you have used 1.1 in the last 6 monthes? how
many of you keep 1.1 in some backup box of disks collecting dust?)
Also, consider that if someone revises the board for 2000/500 then
they would be unable to boot with 1.1.  Also it sounded as if
auto-config would add complexity (and thus $$$) to the board. 
I can't think of any programs offhand that won't let you modify the
startup sequence, but I can think of a couple that will die because
of autoconfigured fastmem.

As for chip configuration, 256Kx4 are more expensive, but getting 32
1Mx1 is also very expensive ($1280 at $40/chip [last price I've seen
for 1Mx1]).  Granted that you get 4 Megs, but I don't really think
that I would actually make use of 4MB, and I don't have $1000 to
spend on memory for the MINIMUM configuration, with 256Kx4 you get
1 MB for c. $300.  I think that 1MB of 32 bit ram, should hold me for
quite some time (especially since I've got 2MB of 16bit FastRam).
