Graphics card in Personal workstation

[Eugen Wintersberger <eugen.wintersberger@jku.at>]

Hi there 
 I got a nice Digital Personal Workstation 600au. Unfortunately nobody 
could tell me which hardware is mounted inside. However, except the 
graphics card all hardware has been autodetected by the system (Debian
3.1R0a for alpha). 
Has anyone an idea what kind of graphics card I have? 
lspci produces the following output:

0000:01:04.0 VGA compatible controller: Cirrus Logic GD 5430/40 [Alpine]
(rev 47) (prog-if 00 [VGA])
        Flags: medium devsel, IRQ 32
        Memory at 0000000009000000 (32-bit, prefetchable) [size=16M]
        Expansion ROM at 000000000a000000 [disabled] [size=16M]

0000:01:05.0 Display controller: Intergraph Corporation: Unknown device
00eb (rev 40)
        Flags: bus master, medium devsel, latency 16, IRQ 33
        Memory at 000000000b000000 (32-bit, non-prefetchable) [size=32K]

I have no idea what it is ;). Does anybody know this thing?
Is it supported by XFree86?
Thanks 
 Eugen
