I mostly dont understand that, the ubuntu forums suggested no better
fixes for the ide device issues than installing a different kernel,
which I did with dpkg, i didnt do any compiling or anything, I dont know
if it really counts as a 'custom kernel' or maybe just an alternate kernel?

I set it up by this method:
http://quozl.netrek.org/bp3-usb/
just using the usbserial module and kppp to dial it

as yet I have not been able to ping anything on the lan, i dont know how
to make my linux pc the access point, or initiate an ad-hoc arrangement
- i follow various how-to's and i get nowhere

that statement turned out not to be entirely true, if I redial the modem
after I activate eth0 ppp0 becomes the default gw again
