I am using 1.4rc4 livecd (stage1 only) and have an orinco lucent silver card wireless as my only means of net access. I cannot make card work. I tried booting first with no options, then modprobed the various pcmcia wireless modules. No way to get card recognized (in slackware - same kernel, it is an orinoco.o module). I then tried to load kernel with dopcmcia option. It then gives beeps, and exits with errors on loading. After load, any attempt to remove card yields: i82365.o: infinite loop in interrupt handler....some numbers. It also tries to use the prism driver. Sorry I have no more specificsm but I will get any info needed. The point it, there seems to be a bug in the basic pcmcia loading package
please try latest experimental livecd www.gentoo.org/~livewire has different pcmcia drivers/tools forwarding to laptop dev also.
old bug, reopen if necessary
