Hi Tobias,

Thanks for the reply. Acceleration is not an issue, but no support for 
text mode is, 8^(.

Does your remark about 3.19rcX refer to kernel 3.19? I just ran the 
Fedora updates and it has installed 3.18.3-201. If I need to wait for 
3.19, I guess I need to be patient for a while longer.

I am assuming that 3.19 will bring text support and basic graphics?

BR
