Using Centos 5.7 and SRS 5.2, everything works perfectly except that the keyboard repeat rate is far too slow.
Apart from the default Gnome keyboard repeat settings I've tried the following without any luck:
Added '-ar1 400 -ar2 100' to XMOREOPTS
Added '-ar1 400 -ar2 100' to Xorg command
Interestingly/frustratingly enough, if I use the Gnome System->Preferences->Keyboard preferences to change the setting and immediately hold a key down in a terminal, it works for ~20 characters before slowing down again. So the Gnome settings are working but something is over riding them on next poll.
FWIW, Sunray is a 2FS model.
Any thoughts greatly appreciated,
