Module: SOURCES                       Tag: LINUX_2_6_20
---- Log message:
- function parameters are taken from stack instead of registers
  it was our default kernel behaviour before 2.6.20.
- this is only for i386 arch
- the main purpose of moving to the (slower) method is compatibility
  with binary-only kernel blobs like HAL from madwifi-ng.
- tested with 2.6.20-rc4, nvidia and madwifi-ng aka ath_pci
