Is it doable to get an 2.4 linux kernel running on the efika? I noticed that the debian distro is also using the 2.6 kernel. Using an older kernel and gcc i might be able to compile miniglx (fdbev/dri mesa). Should i bother trying or is that an dead end.
It's REALLY not worth it.
Stick with 2.6. If you need to use 3D then try DirectFBGL (it isn't Matrox-specific by any means) and try asking on the DirectFB and Mesa mailing lists.
DirectFBGL is also a part of Mesa and is well maintained. Just use the later versions of Mesa (7.x) and start from there. Between the support already in Mesa (implements a software renderer, would be useful to just test) and the DirectFBGL 0.9.25 version (which uses DRI) everything is there.
I think the errors you had on compiling were *NOTHING* to do with code quality on these packages. Going backwards and using older code will only cause more problems in the long term.. this isn't PowerPC-specific, but a problem of your build system and the tools, so I would really recommend talking to those developers :)
