Hi Paul,
In the mean time I did some extra changes :
- updated kernel to latest version : then the module from VIA doesn't work anymore
- I was affected by a bug regarding the use of the second SATA connector ( see
Bug 8563 - pata_via: Does not work with 2nd drive attached )
For both reason I then decided to patch the source against 1) the VIA unichrome patch ( unichrome_patch from VIA Linux Portal ) and 2) the SATA patch from the link above.
Now the whole is perfect.
Regarding the use of the VIA unichrome patch, I installed first the binary driver, and then after recompilation was having my own module. But you still need the binary driver for the GL libraries.
I have created .deb of my kernel binary and modules, if it can help someone, I don't mind dumping it somewhere. With this kernel I do raid 1 on SATA to encrypted LVM, 3D and hard accel ( well this is the DRM part of the patch right ? ).
Now for your questions :
a)
uname -r
2.6.24.3-epia6
That's my customer version now, it has been build using source from 2.6.24 shipped with 2.6.24-19
b) you get this error message after upgrading your kernel version. The binary module shipped with the binary driver is build against the first kernel of ubuntu 8.04 LTS, after doing an upgrade it doesn't work anymore.
c) yes you still see it, but you can go past it :

d) no I am using totem shipped with ubuntu ( based on xine ).
I haven't tried VeXP / VeMP but will probably if I can get hold of it
