Kernel 2.4.x video problems

I've got a few questions pertaining to video in recent kernels (2.4.x, x >=
10) on both an iMac DV SE/500 (Summer 2000, ATI Rage 128 Pro) and a G4 Dual
533 (ATI Radeon).
First of all, I can only boot the iMac using the novideo kernel argument.
If I attempt to use video=aty128fb with or without any vmode parameters, the
screen just remains black. I can type blindly and reboot, and got a dmesg.
Nothing out of the ordinary. If there are any ways of getting verbose
messages from the kernel or the driver itself, I would be rather grateful.
Second, the G4/533 works fine with no arguments, but it remains in 640x480,
8-bit color. As soon as I try to get some accelerated video using the
Radeon FB driver, the screen remains blank as in the iMac. A dmesg this
time does in fact yield a message: "radeonfb: could not claim FB region" or
something similar (not by the machine at the moment). Anyone know what's
I can provide full output of either of the dmesg's or lspci's or whatever.
Thanks very much,
