So this means Elbox drivers only support 128MB gfx mem with their drivers. 
Yes I do need 200MB or more of gfx card mem.
I wish Elbox would have just explained this on their website.
The drivers(s) support more than 128MB.
BUT ... there are different Radeon 256MB designs out there.
Some of them have 256MB in ONE block, others came with 2 parts a 128MB.
P96 is only able to handle linear memory (one block).
So its not a Elbox-radeon or xyz-radeon-driver problem ... P96!
V0.99 limitation to 128MB is only until i changed some code to place the spritegfx at the beginning of memory .. the sprite-pointerregister is only able to adr. 128MB also on oneblock 256MB radeons.
@soviet: R100 is not supported, only R2xx (8500AGP - 9250PCI).
