uses the DMA/blitter enabled kernel to perform system to video ram pixmap
copies

This patch makes Xglamo use the kernel to for pixmap migration to video ram,
using DMA.
To make Xglamo use this DMA thing, you need to "export USE_DMA=1", otherwise, a
plain memcpy will be used for pixmap migration.
To use this patch, you need a kernel patched with
