X on Pismo failing to start!

[Suzanne Payne]

I'm having major problems getting the XF86Config correct for my Pismo.  I 
installed via the text install as I originally had a problem with the 
network settings when I tried the graphical installer.  Ironically I could 
get X to start after the graphical install (why oh why oh why didn't I save 
the XF86Config file from that install!!!), but I had no network and 
couldn't work out how to manually get the network up and running - so I 
thought another reinstall from scratch would be easier! :-(  This is now 
the third time I've reinstalled YDL 3.0 in an effort to get the installers 
to set everything correctly!

The relevant section of the XF86Config says:


Section "Device"
	Identifier	"ATI Rage 128 Mobility"
	Driver		"r128"
	Option		"UseFBDev"
	VendorName	"ATI Rage 128 Mobility"
	BoardName	"ATI Rage 128 Mobility"
EndSection


But when I startx it crashes out with no screens and the log says:


(II) Loading sub module "fbdevhw"
(II) LoadModule "fbdevhw"
(II) Reloading /usr/X11R6/lib/modules/linux/libfbdevhw.a
(WW) Open /dev/fb2: No such device
(WW) Open /dev/fb3: No such device
...... (it tries to open up to /dev/fb7 with the same result)
(EE) R128(0) failed to open framebuffer device



/dev/fb0-31 do exist!  I've checked!


I've run Xautoconfig and its XF86Config file (which uses the driver "fbdev 
instead of "r128") also crashes out with another FBDEV error:

(EE) FBDEV(0): FBIOPUT_VSCREENINFO: Invalid argument
(EE) FBDEV(0): Mode init failed


Getting sooooooooooooooo annoyed :(

Anyone?
