Well... I have also extensively used the IDE interface on
the M5249C3 board. And its layout is essentially the same
as the 5272. I don't recall any specific IDE problems on
that setup.

That just sounds very strange. I use the M5272C3 _alot_.
In fact it is my main test board for uClinux-dist releases.
(Offcourse no IDE). I don't have any specific memory problems,
and it has way more than 2MB of free RAM after booting to
a shell prompt.
