Wireless + FLOSS = no sleep? Damn mengos!

So, Finally I was able to get my PCI wifi card running under Linux.
I've bought it weeks ago, Whatever I do the box keeps freezing when I bring up the interface.
ndiswrapper is freezing at random points, And finally when I was able to use the GPL'ed driver, I didn't get a connection.

I tried with 6 kernels or so.
I decided to get an old P2 or so and try and yes! IT WORKED.
The damn CNET CWP-854 worked under Linux with the rt2500 driver.
Now I'm enjoying wireless at home with my GNU/Linux semi-access point.

I'll be giving a presentation tomorrow in the FLOSS conference About the state of Arabic FLOSS desktop and I'll be demoing things on the 3rd day. And for sure I didn't prepare anything as I thought that the whole thing is next week. I slept for 2 and a half hours yesterday and I can hardly type this!
I wonder how am I going to work and then go attend the conference, And work on my presentation after this ?
