Hi all, I've finally managed to make my Slackware work on Asus M3700N notebook.
I've also managed to connect to internet via Nokia 3650 bluetooth using MSI USB Bluetooth dongle. Sound works as well. 1400x1050 resolution also works fine. Internal modem is working.
All this I've posted as an article on my website. There you can get a working kernel config and other files as well. Feel free to submit any bugs to me.
