Question Wireless RT2500, "Device or resource busy" in Ubuntu

I have an internal Ralink RT2500 chipset in my Packard Bell laptop. I recently installed Dapper which apparently supports it from the off, but it didn't work. I've followed the instructions on the guide at '' and installed the latest CVS drivers, but still it doesn't seem to come to life. I've entered the correct ESSID and WEP key into the Network Settings box, but no lights flash on my router when I click ok.
If I type in 'lshw' it comes up with:
*-network:0 DISABLED
             description: Wireless interface
             product: Ralink RT2500 802.11 Cardbus Reference Card
             vendor: RaLink
             physical id: 11
             bus info: pci@00:11.0
             logical name: ra0
             version: 01
             serial: 00:10:60:61:27:59
             width: 32 bits
             clock: 33MHz
             capabilities: bus_master cap_list ethernet physical wireless
             configuration: broadcast=yes driver=RT2500STA driverversion=1.1.0 CVS link=yes multicast=yes wireless=RT2500 Wireless
             resources: iomemory:44000000-44001fff
So i believe i have set up the drivers correctly, but if i try and do 'ifup ra0' or run Wireless Assistant, which i hope to manage my networks with in the end, it will give the error "SIOCSIFFLAGS: Device or resource busy". I've tried reinstalling the drivers a few times but that didnt help. I've also tried adding both pci=noacpi & pci=biosirq to the kernel command-line thing at start up, as suggested by sites found with google. I also found a suggestion that I should turn off PnP in the bios, but it doesnt seem to have that option, my bios being restrictive Packard Bell rubbish. I added in the nobiospnp command too, to see if that affect anything, but it seems nothing will work. I assume there is conflict with another program or drivers, but i really dont know where to look or what to do.
Any help would be much appricated.
