vesa.ko do not load with ASpeed AST2300 chipset

[Florian Millet]

Hello everyone,

I stumbled into a problem with a gigabyte motherboard (GA-6PXSV3), more
specifically the integrated video chipset on it. The chipset is a ASpeed
AST2300 and supposedly handle up to a resolution of 1920x1200.
( for reference : http://www.aspeedtech.com/products.php?fPath=20&rId=200 )
My problem is not under X.org but in console mode, the vesa.ko module
refuses to load with this chipset giving me a :

module_register_init: MOD_LOAD (vesa, 0xffffffff81214000, 0) error 19

When trying to see which resolution I can use in console mode with
`vidcontrol -i mode` I get only one line :

3 (0x003) 0x00000001 T 80x25        8x8    0xb80000 32k 32k 0x00000000 32k

Unfortunately recompiling with VESA_DEBUG=1 does not yield any more
information as to why it refuses to load (compiled in kernel or as a
module).
Enabling the define MODE_TABLE_BROKEN in /usr/src/sys/dev/fb/vesa.c
changes nothing.
This problem has been confirmed on FreeBSD 10/STABLE and 9.2/RELEASE.

I tried to flash the vbios to the latest version but their utility tells
me it is impossible since the version installed is "invalidate" ...

`pciconf -lv` gives me :
vgapci0 at pci0:8:0:0:    class=0x030000 card=0x20001458 chip=0x20001a03
rev=0x21 hdr=0x00
    vendor    = 'ASPEED Technology, Inc.'
    device    = 'ASPEED Graphics Family'
    class     = display
    subclass  = VGA

Does anyone has an idea as to why I can't have any other resolution in
console mode ?
I can give access to the machine via ssh if it helps debugging the problem.
