      I managed to install R5 on a PowerBook G3/300, but I could not get accelerated
video running. I used "video=atyfb:vmode:14,cmode:32,mclk:xx" with xx from 63 to
73, but got always the "garbage screen". Has anyone had better results?

Which kernel version is shipped with R5? Does the kernel tell you the estimated
clock crystal frequency (XTAL) during the initialization of the ATI frame
buffer device (atyfb)? If not, they're using a kernel without the clock crystal
frequency estimation patch (present in 2.3.6).

The kernel version is 2.2.6. If I start with the "No video driver" option
checked (from BootX), the startup messages siplly tell me that

MacOS display is /pci/ATY,RageLTPro
Using unsupported 1024x768 ATY,RageLTPro at 82801000, depth=32, pitch=4096
Console: switching to colour frame buffer device 128x48
fb0: Open Firmware frame buffer device on /pci/ATY,RageLTPro

Unfortunately, I can not telnet yet to the PB, so I can't see the startup
messages when I use the atyfb option...

Hence you need the clock crystal frequency estimation patch to be able to use
atyfb and acceleration.

Copying drivers/video/atyfb.c from 2.3.6 should do the trick.
