Downgrade hx2795 from WM5 to PPC2003

[plsmth]

Partly for nostalgic reasons and partly because I want to run an old application, I need to downgrade my 2795 from WM5 to PPC2003. HP has already told me this is not possible but IIRC the 2795 originally shipped with PPC2003. I purchased the 2795 used and it came with WM5 so I do not have a PPC2003 ROM, is it available from a source other than HP?

Thanks.

After talking with HP again the hx2795 never shipped with PPC2003, but its predecessor the hx2725 did. So if I really want PPC2003 on my 2795 it will have to be hacked on.
