+
+ To do (maybe?):
+ - include Information about XFree86 and/or Accelerated X
+ (needs to change configure-skript, to see, if Header-files are available !)
+ - maybe also include information about the video-framebuffer devices
+ - rewrite detection-routines (maybe not to use the /proc-fs)
+ - more & better sound-information
