Warren, thank you, but this doesn't help. I've added:

Section "Monitor"
	Identifier   "Monitor0"
	HorizSync	30-50
	VertRefresh	60
EndSection

Section "Device"
	Identifier  "Card0"
	Driver      "mach64"
	BusID       "PCI:0:2:0"
EndSection

Section "Screen"
	Identifier "Screen0"
	Device     "Card0"
	Monitor    "Monitor0"
	DefaultDepth	24
	SubSection "Display"
		Viewport   0 0
		Depth     24
		Modes	"1280x1024"
	EndSubSection
EndSection

This is an LCD monitor, and the manuf. specs state
	max res 1280x1024
	horizontal: 30-80
	vertical: 50-75

I tried modes down to 800x600 - no change.

I noticed also this error: 

(EE) [drm] drmOpen failed.
(EE) MACH64(0): [dri] DRIScreenInit Failed

should I add device drm to the kernel?
Just to remind, this is sparc64.

wow.. you mean on sparc64? I didn't know.
If it'll work on sparc, this would be great. There
are many more radeon 7000 on offer than pgx64.

many thanks as always
