10.1 Beta 3 - Quanta monitor drivers missing

I just tried to install Beta 3 on my laptop (Acer Extensa 4100, also known as Travelmate I believe). It requires the Quanta driver for the display (1280x800 LCD), the default LCD values for a 1280x800@60/75Hz don't work - I just get a black screen. I'm currently working through other general settings under Vesa and LCD, but until now I haven't found a single monitor setting which will display anything... Can we please have the Quanta settings back? Dave
