I have a Compaq Presario 1200 XL125 laptop (Trident CyberBlade video card). Anaconda correctly detects the video card, but then misconfigures the LCD (it fails to detect screen type) and so GUI install is not possible. This is a major regression from 7.1, which installed fine on this laptop.
Please try the update disk to anaconda which was posted to the testers-list last week and let me know if it helps.
I tried the second update disk posted (update-disk-07192001.img), and it boots in GUI mode, but text is not rendered correctly (looks like an incorrect code page issue -- in the "Online Help", for example, all chars are rendered as blocks).
This defect is considered SHOULD-FIX for Fairfax.
When you boot into GUI mode is there a penguin in the upper left corner, indicating you are in frame buffer console mode? This is probably a dupe of bug 49972.
It is in frame-buffer mode
The characters in the help being rendered as blocks should be fixed in beta3
