agp_backend_initialize() failed on ServerWorks CNB20LE

[Maciej Soltysiak]

Hello,

On a server with ServerWorks CNB20LE and CONFIG_AGP_SWORKS enabled
I get these upon bootup:
Linux agpgart interface v0.101 (c) Dave Jones
agpgart: unable to determine aperture size.
agpgart: agp_backend_initialize() failed.
agpgart-serverworks: probe of 0000:00:00.0 failed with error -22
agpgart: unable to determine aperture size.
agpgart: agp_backend_initialize() failed.
agpgart-serverworks: probe of 0000:00:00.1 failed with error -22

lspci -vvv shows (i skipped the IDE, ISA and NIC lines):

The only problems I have that *may* be related to these messages is the
fact that when I boot into X and try to switch to a text console, the
screen gets garbled and freezes, the server works fine besides the
screen throwing trash at me.
It is not a big issue, but maybe anyone would like to know.
Or enlighten me if it

Regards,
Maciej
