he he. it's better now, the yent_probe_handler is there at least :)

so can you try these two things?
- make sure no card is inserted when yenta is loading. insert it when the
  whole pcmcia thingy is up
- try to just remove the followin code in yenta_probe_cb_irq() in yenta.c:
        /* disable ISA interrupts */
        bridge_ctrl = config_readw(socket, CB_BRIDGE_CONTROL);
        bridge_ctrl &= ~CB_BRIDGE_INTR;
        config_writew(socket, CB_BRIDGE_CONTROL, bridge_ctrl);

now that i think about it i can't remember why i put it there in the
first place...it's not needed as far as i can see. also the opposite in
yenta_probe_irq() is not needed...this thingy is only for the functional
interrupt, not for the CSC.
