Linux/68k has an new ioctl for setting the keyboard repeat rate
1999-03-17
Linux/SPARC modifications by Jeffrey Connell <ankh@canuck.gen.nz>:
It seems that the KDKBDREP ioctl is not available on this platform.
- However, Linux/SPARC has its own ioctl for this, with yet another
- different measurement system. Thus, try for KIOCSRATE, too.
