Depends whether it would patch to 2.4.18 sucessfully or whether it is 
designed to patch to 2.4.26 or 2.4.27.  If I have to do work to get it 
to patch, then the time might be better spent porting 2.6.x to my board :)

I can confirm that the 128MB DOC I received in Australia definately DOES 
NOT work.  i.e. it looks like it has the new ASIC embedded in it.  A 
friend of mine in the USA also sees the same thing on his newly received 
128MB DOC.  Therefore I think the M-System docs are wrong.

Anyone know about the 96MB DOC2000 ????
Is it an old style or new style DOC2000 ????
