[Linux-fbdev-users] X over fb: "EGA/VGA planes are not yet supported by the fbdev driver [1]"

[<gl...@ds...>]

Hello everyone

Trying to get the xserver (Knoppix 3.8 XFree86 4.3.0.1) over framebuffer. 
The hw is the following:

0000:00:02.0 VGA compatible controller: Intel Corp. 82852/855GM Integrated 
Graphics Device (rev 02)
0000:00:02.1 Display controller: Intel Corp. 82852/855GM Integrated 
Graphics Device (rev 02)

(btw, why do I get 2?) If I try he intelfb kernel driver, I get

intelfb: intelfb_init
intelfb: Framebuffer driver for Intel(R) 830M/845G/852GM/855GM/865G/915G chipsets
intelfb: Version 0.9.2
intelfb: intelfb_setup
intelfb: no options
intelfb: intelfb_pci_register
intelfb: fb aperture: 0xd8000000/0x8000000, MMIO region: 0xe8180000/0x80000
intelfb: 00:02.0: Intel(R) 855GME, aperture size 128MB, stolen memory 32636kB
intelfb: fb: 0xdb012000(+ 0x3012)/0x400000 (0xd1992000)
intelfb: MMIO: 0xe8180000/0x80000 (0xd1e00000)
intelfb: ring buffer: 0xdb001000/0x10000 (0xd1981000)
intelfb: HW cursor: 0xdd24000/0x1000 (0xd1991000) (offset 0x3011) (phys 0xdd24000)
intelfb: options: vram = 4, accel = 1, hwcursor = 1, fixed = 0, noinit = 0
intelfb: options: mode = ""
intelfb: Non-CRT device is enabled ( LVDS port ).  Disabling mode switching.
intelfb: Video mode must be programmed at boot time.
intelfb: cleanup

I tried setting "vga=..." - no way. With vga16fb I can boot with the 
framebuffer, i.e. it will be used by the console, but I cannot get X 
running over it. I can run it over i810 X driver, but I need fb... 
XF86Config-4 (BusID under "Card1" is just a test - tried without any too) 
and XFree86.0.log attached.

BTW, the reason why I want to run X over fb is, that I need to use 
touchscreen, about which I read in a HowTo, that it only works if X runs 
over fb, is it still true?

Any hints would be greatly appreciated
Thanks in advance
