jalind: the model of your orinoco is much newer than what WLANjogi has. WLANJogi has the legacy orinoco known as the 5V Cardbus card. Those cards won't be displayed via lspci output, supports only 802.11b and requires special firmware to do monitor (it can't really do injection)
The model of your card is the much latter one that proxim later bought out the orinoco name. Yours is the one that should be equipped with atheros chipset, supports a/b/g uses 3.3V and is the latter pcmcia based card. Your card is also visible via lspci output and it doesn't require special firmware just to use rfmon mode.
Here is an old wiki entry of the legacy orinoco:

Here is an old wiki entry of the latter/current orinoco:

WLANJogi, the last working version of backtrack suitable for it was backtrack 2 for orinoco, you will need to flash your orinoco to a much older version in order to take advantage of rfmon status but don't expect for injection mode because the lack of development on the driver inhibits injection capabilities.
On backtrack 4 the orinoco driver is in staging, its not fully supported yet but the development is ongoing to improve the driver for usage on current kernels. I have previously had it working under another pentesting distro with a much latter kernel at the time with `soft' flashing but I could not get rfmon to fully show anything. Don't panic, there are works every now and then underway for some support on these legacy orinoco chips.
