The better long-term idea is to avoid Xfbdev and use Xfree86 + new
driver, based on fbdev.

There were measurements of memory usage by Xfbdev and Xfree86 recently,
the difference is small (~1.5Mb of RAM). And better, this gap shrinks,
as there is work underway in Xfree86 to make it consume less memory.
