UnitSizeFactor != 1 ?

UnitSizeFactor != 1 ?

[pla]

Okay, new odd question.  Still using a 32mb DOC2000.  Everything
works well, until...
 
I try running XFree86 4.1.0, tried the C&T driver (I have a ct65555),
the FB driver, and the VESA driver.  All produce the same results,
namely, inconsistant "really odd" errors (such as various modules
looking like invalid modules, random sig-11's, etc).  By loading
all the X-stuff into a ramdisk, I can at least get the server to
start, but it locks up within a few seconds.  If I kill the server
before the lockup, I get back to a prompt and the system still
locks up within a few seconds (sometimes so badly that magic SysRq
functions don't respond, and even when they do, it won't finish
a sync or unmount).
 
This occurs with 2.4.8, MTD snapshot 20010812, and DOC stock firmware 4.2.
 
Now, about the subject line...
 
I tried upgrading the DOC to the newer 5.0 firmware, and I get the
error "Sorry, we don't support UnitSizeFactor of != 1 yet" at boot.
 
Both of these seem like at least somewhat serious problems, but the
latter ends up leaving me without a /dev/nftl/ entry, so I consider
it the more serious of the two, thus my subject line.
 
Thank you for any advice you might offer.
