- Refined internal interface in keyboard drivers so that: 1. the side effect of device probe is kept minimal, 2. polling mode function is added, 3. and new ioctl and configuration options are added (see below). - Added new ioctl: KDSETREPEAT Set keyboard typematic rate. There has existed an ioctl command, KDSETRAD, for the same purpose. However, KDSETRAD is dependent on the AT keyboard. KDSETREPEAT provides more generic interface. KDSETRAD will still be supported in the atkbd driver. - Added new configuration options: ATKBD_DFLT_KEYMAP Specify a keymap to be used as the default, built-in keymap. (There has been undocumented options, DKKEYMAP, UKKEYMAP, GRKEYMAP, SWKEYMAP, RUKEYMAP, ESKEYMAP, and ISKEYMAP to set the default keymap. These options are now gone for good. The new option is more general.) KBD_DISABLE_KEYMAP_LOADING Don't allow the user to change the keymap.
