I find it useful to put kbdrate in my /etc/rc file so that the keyboard
rate is set to something that I find comfortable at boot time. This sure
beats rebuilding the kernel!

+ Added patch for AUSTIN notebooks from John Bowman
+ (bowman@hagar.ph.utexas.edu)
+
+ Linux/68k modifications by Roman Hodek
+ (Roman.Hodek@informatik.uni-erlangen.de):
+
+ Reading/writing the Intel I/O ports via /dev/port is not the
+ English way... Such hardware dependant stuff can never work on
+ other architectures.
+
+ Linux/68k has an new ioctl for setting the keyboard repeat rate
+ and delay. Both values are counted in msecs, the kernel will do
+ any rounding to values possible with the underlying hardware.
+
+ kbdrate now first tries if the KDKBDREP ioctl is available. If it
+ is, it is used, else the old method is applied.
