Since you're using a dell, why don't you buy the Wireless N card (for those who are trying hard for wifi)
This broadcom card works with COMPAQ laptops
RM 100 (yeah bit pricey) but its the same wifi card which can be found in MacBook Pros , its native - meaning it works out of the box without any hacking , etc
http://forum.lowyat.net/index.php?showtopic=884377&hl=I just ordered mine. Stupid Atheros card doesn't want to work with my U1010 !
Suk , that one works with your laptop. Check with the seller. Its the only card that we can find in Malaysia for laptops which works as Airport
Oh by the way , its very hard to find Dell 1390/1490 , if anyone knows where to get them let me know
Anyway things that work with Tablet Hack (will post pictures later)
1. Graphics card (obviously , duh its GMA 950 - it has to work)
2. Bluetooth (works out of the box)
3. Basic keyboard + mouse (had to install PS2 kext) , + USB + Sleep (sleep works but after that it goes too slow)
4. Touch-screen (My tablet has two modes in bios , one is touch screen and the one is in tablet. In touch screen mode , with Windows Vista/XP Tablet - I can write and use it as a tablet pc , but its not supported in Linux. However in OSX , it works out of the box and it shows me Ink. I can write on the screen)
5. Ethernet (Works out of the box)
Things that I thought would work but didn't work
1. Sound - AppleHDA keeps on giving me kernel panics. Figuring it out why
2. WiFi - expected this guy to work. Its Atheros MiniPCIe , but it doesn't work . Ordered Broadcom 802.11n card in order to fix this
