[syslinux] How to set a portrait mode screen using i915 driver?

[SCU Rock]

Sorry if I did not state my question properly. By referring to graphic
image, I meant to say a disk linux image that would be loaded by the Live CD
isolinux.cfg file. How can I use i915 feature to load the disk image so that
it boots off a portrait display in portrait mode?

The motivation is to run linux on tablets that can be turned into portrait
mode. I think by using i915 feature, I maybe achieve this.

You have to size the image properly.
