So if he had a 256 mem stick, and is using 32 megs as video "shared" memory, he would try it first by hitting escape when lilo first comes up, then type in "linux mem=224M" (don't forget the last capital M) hit enter and see if he can use the video modes he wants. if that works, write back, and someone will explain how to make the change permanent with each boot. he might also want to consider that sizes that are "not standard ones" are for laptops (such as "1024x480") or devices with a display that is not the same rectangle as most monitors used to be
