vesafb on Savage4

vesafb on Savage4

[Miernik]

I have got a video card which identifies itself (before BIOS boots) as
S3 86C395/396/397. 

My lspci -vv output is:

The kernel is installed from a binary:
http://ftp.pl.debian.org/debian/pool/main/k/kernel-image-2.6.7-i386/kernel-image-2.6.7-1-k7_2.6.7-2_i386.deb

When the system is booted, in /var/log/kern.log there is:

Aug  3 13:52:19 localhost kernel: vesafb: probe of vesafb0 failed with error -6

przehyba:~# modprobe vesafb
przehyba:~# lsmod | grep vesafb
vesafb                  6688  0

przehyba:~# ls -l /dev/fb0

From these posts I can see that vesafb does work on Savage cards:

http://www.ussg.iu.edu/hypermail/linux/kernel/0011.0/0263.html

If I try savagefb, I get the same error that is decribed here:

http://www.directfb.org/mailinglists/directfb-dev/2003/09-2003/msg00044.html

How can I get any framebuffer working on this card?

The error is -ENXIO and in vesafb it means that your graphics card failed to 
go to graphics mode.

Can you post your dmesg and kernel config?

It finally worked, when I added
vga=0x314 video=vesa:mtrr,ywrap 
to my kernel parameters. 

With only vga=8 as a kernel parameters, and then trying
modprobe vesafb
fbset
it didn't want to work, should it?

No, the stock kernel vesafb cannot be compiled as a module, nor can you use 
fbset, unless the distribution patched the kernel with a modified vesafb (ie, 
vesafb-tng).
