* Xbus protocol version: 2.4 (Zaptel 1.2.12/1.4.0 had 2.3).

  XPS Init scripts renamed accordingly.
* Performance improvements for multi-XPD (span) devices.
* Astribank BRI driver (in next commit).
* Changes under /proc:
  - XBUS and XPD numbers have two digits.
  - Every script wildcard should be replaced from XBUS-? to XBUS-[0-9]*
  - Added /proc/xpp/XBUS-*/XPD-*/blink: echo 1 to start and 0 to stop.
* Several countries (South Africa, UAE, anybody else) require a shorter
  ring delay. Adjust FXO reg 0x17 (23)'s bits 0:2 to 011.
* Use tasklets to move most of the interrupt PCM copying out of the interrupt.
* Debugfs-based code to dump data to userspace (used to debug BRI D channel).
* Pretend every 2.6.9 actually has later RHEL's typedefs.
* fpga_load supports /dev/bus/usb .
* Fixed physical order sorting in genzaptelconf.
