Sorry if I didn't make myself all that clear - but that is exactly
what I have tried and it doesn't work. During startup X detects the
built in display and sets the maximal resolution to 1024x768. 

It simply go above if X is started with the built in display active
[1]. If I disable the built in display and _then_ start X it still
doesn't work.

[1] My laptop has three settings: build in only; external only; both
built in and external. Can be switched between with Fn-F7

I tried adding the monitor and screen sections below to my
XF86Config-4 and then making it the only screen sections mentioned in
my ServerLayout. After restaring X (with the build in display
disabled) the external display works just fine in 1280x1024.

Section "Monitor"
	Identifier	"L1710B"
	HorizSync	30-83
	VertRefresh	56-75
	Option		"DPMS"
	Option		"SyncOnGreen"
EndSection

Section "Screen"
	Identifier	"External Screen"
	Device		"T22 Savage"
	Monitor		"L1710B"
	DefaultDepth	24
	SubSection "Display"
		Depth		24
		Modes		"1280x1024"
	EndSubSection
EndSection

I hope this helps :)
