from ds linux site:

Run light enough to power a 486DX with 16MB of Ram

[mips]

is it possible ?

No. You would have to port DSL to the MIPS cpu architecture I suppose if you wanted to run it on a PS2.

i checked out the playstation2-linux site, but according to it ps2 linux isn't available in the US anymore.

Check Ebay or import from the UK/Europe ?

mm sorry, but wasn't the playstation 2 based on a pentium 3 700MHz with some nvidia graphics chip and 64mb ram? I know it has been done... using some game to enter linux or something..
