Does Slax/BT3 have a simple way to update linux?

I'm testing different wireless nic s, and the Airlink 11 awll3025v2 seems to need an updated kernell version (as many many other drivers and patches).

Linksys wusb54gc worked really good (monitor and injection), with the driver that is posted on the wiki . But sometimes 1/20 it freezes aireplay.

Thanks in advance.
