I just installed booted the Gentoo 2005.1 live CD with a D-Link 690-txd pcmcia card.
It was a bear to get it to work, until I typed "dmesg | less" and read the logs. They suggest booting the kernel with the option "irqpoll" enabled.
So I rebooted, and typed "gentoo irqpoll dopcmcia" at the boot prompt.
It worked !!!
Hope this helps someone else.
