IIRC you need to do a text mode install on the Dell.

Are you including the ATI frame buffer code or not - I assume yes.

2.2.17pre15
o	ATI video fixes for PPC				(Benjamin Herrenschmidt)

So if thats the one that does it perhaps you can go over it with the powerpc
folks ?

Hard to be sure. Without knowing precisely which board they have and which
options you used I can't guess which code path changed

2.2.18-25 DELL Laptop Video Problems

[Jeff V. Merkey]

2.2.18-25 with Frame Buffer enabled will frizt and trash LCD displays
on DELL laptop computers when the system kicks into graphics mode,
and attempts to display the penguin images on the screen.  It 
renders the anaconda installer dead in the water when you attempt 
even a text mode install (not graphics) of a 2.2.18-25 kernel (and 24)
on a DELL laptop.  Is there a way to turn on frame buffer without 
kicking the kernel into mode 274 and killing DELL laptops during
a text based install?

Alan,

Id there a workaround for this for DELL laptops.  Frame buffer needs
to be enabled because you don't really know what system you are on
until after it installs, and the X probing stuff needs it enabled in
order to properly detect the hardware.  Any ideas?

Can't.  When 2.2.18-25 boots up, when it tries to flash the penguin
image on the screen, it fritzes the laptop.

Use the VESA fb driver instead of the ATI fb driver. I have been doing so
ever since i got my DELL Inspiron 7500: the ATI driver won't recognize the
Rage Mobility chips (well, i could convince it to do so but the 1400x1050
LCD panel timing never worked...)

Can you enable both at the same time?  It's an installer issue with laptops
and I need tobe able to detect whatever is running.

IIRC you can choose at boot time using a kernel parameter.

Then this is the vga=271 stuff?

No, that's just selecting the VGA resolution. I am referring to the
video parameter:

  video=<driver>:<option>[,<option>,...]

Look at linux/Dokumentation/fb/modedb.txt.

Thanks!  I will.   I did have VESA FB enabled, BTW and I still see the 
problem.

It's not in my tree (2.2.18), the only documentation I could find was
the source code. Anyway, it seems that atyfb gets a precendence over
vesafb and screws up the LCD. Right now I use the following kernel params:
video=atyfb:off video=vesa:mtrr vga=795

For reference this is Dell Inspiron 5000, lspci -vv says this:

My fault: i was looking at a 2.4.0-test* tree... But i think that information
holds true for 2.2.* as well.
