The debian squeeze image is intended to run on WDTV Live/Plus, it won't run on WDTV Gen1 (and I haven't seen a debian root bin for Gen1 yet).
Gen1 and Live/Plus are NOT binary compatible! (MIPS <-> MIPSEL)
If you still want to compile for Gen1 I think your only option is the GPL source from WD and cross-compiling.
PS: Outing yourself as a n00b in this forum section is a bit dangerous... (read the section heading!) This is the section for the ones knowing what they are doing and who can live with the potential consequences ;p
