Well in fact it was not intentional. The Tr code was rewritten to work on
linux Alpha. We made a patch against 1.3.70. This patch was included in
1.3.78. PCMCIA stuff vanished when our patch was applied on the source
tree. Here is a patch I made against 1.3.80 (it should work with 1.3.8x).
As I don't have access to PCMCIA I can't test it. All I can tell is that
it compiles fine. Also it doesn't break ISA card code. Can you test it
and tell me if it works ? Thanks
