xf86-video-chips doesn't recognise supported card [amd64 bug?]

[Helge Rohde]

Hello List,

This is from pciconf:

vgapci1 at pci0:3:7:0:	class=0x030000 card=0x00000000 chip=0x00e4102c rev=0xc2 
hdr=0x00
    vendor     = 'Asiliant (Chips And Technologies)'
    device     = '65554 Flat Panel/LCD CRT GUI Accelerator'
    class      = display
    subclass   = VGA

this is the relevant part from my xorg.conf (that used to work under i386)

Section "Device"
    Identifier  "TFTGRAKA"
    Driver      "chips"
	Chipset	"ct65554"
EndSection

However, X doesnt start up. Instead it complains in Xorg.0.log that the chips 
driver cannot find the card (not without claiming that it is supported ;) :

(II) CHIPS: Driver for Chips and Technologies chipsets: ct65520, ct65525,
	ct65530, ct65535, ct65540, ct65545, ct65546, ct65548, ct65550,
	ct65554, ct65555, ct68554, ct69000, ct69030, ct64200, ct64300
(II) Primary Device is: 
(WW) CHIPS: No matching Device section for instance (BusID PCI:3:7:0) found
(EE) No devices detected.

Fatal server error:
no screens found


Any ideas/pointers ?

thanks, 
Helge
