Usually a double-high beep-beep is good.
A high-low beep-boop is not. To explain the tones, the first high beep means PCMCIA support (kernel modules) were loaded. This is for the PCI adapter.
The second high beep means a card was detected, and its drivers successfully loaded.
To configure your device, you look in /etc/pcmcia ... once the above drivers successfully load, the requisite network scripts are automagically run.
So did you configure any files in /etc/pcmcia ?
I recently successfully configured the DWL-500 under SuSE Linux.
The preferred drivers for the D-Link DWL-650 are the linux-wlan-ng drivers that you download & compile yourself. However, I never got these to work.
I did get the orinoco_cs drivers to work, but only after enabling the new kernel PCMCIA drivers (yenta_socket)
instead of the older external drivers.
If the loading of the device driver locks up the PC, pop out the PC card (yes you can hot-swap with the PCI adapter).
If what I've mentioned so far is greek to you, then you have some reading to do.

Let me know if you have any more questions.
Finally, I replaced the DWL-650 with an orinoco Gold PC card, which is much better performing.
