I've had a play with the rt2x00 tree (11c3222a) and hit some problems on my
EeePC 901.

First, I was seeing "SIOCSIFFLAGS: unknown error 132" (which turns out to be
ERFKILL) when trying to bring up the interface. "rfkill list" shows that phy0
is hard-blocked¹; since there's no switch for this, the only way to "unblock"
it is to patch the driver. I used the following patch for this².

diff --git a/drivers/net/wireless/rt2x00/rt2800pci.c b/drivers/net/wireless/rt2x

+               rt2x00pci_register_write(rt2x00dev, GPIO_CTRL_CFG, reg);
+       }
+       return 0;       
 }
 
 #ifdef CONFIG_RT2X00_LIB_LEDS

However, this isn't the end of the problems: I get an oops instead while
trying to bring up the interface (configured via /etc/network/interfaces and
using WPA2; the configuration is known good for rt2860sta).


¹ phy0 is only present when eeepc-wlan is not blocked, which isn't surprising
  because the card is effectively unplugged when eeepc-wlan is blocked.

² I also tried just having rt2800pci_rfkill_poll() just return 0, but that
  makes no difference.
