I am still unsure what exactly caused this. For reference, I also provide my XF86Config file . Note however that all gory details are handled by the Framebuffer device underlying the X11 server. Another XF86Config file has been provided by Fr d ric Pierre. It does not give hardware acceleration either.
Some operations seem faster, some seem slower.
Thanks to Dave Shewfelt for sending it in. You can download my kernel 2.2.10 and pcmcia-cs 3.0.12 modules for 2.2.10 packages. Updated packages for kernel 2.2.12 and matching pcmcia-cs 3.0.14 modules are now available as well. Sound To be done. Pointers are welcome, I am not sure yet how his chipset is supported.
