Palm Tungsten C wifi in Linux

Just noting this before I forget it. Use fc447e3213efb31cb16b5d9a2b0ebb77fbafd131 from git:// with the defconfig. You'll need to load standard RAM prism firmware (pm010102.hex and rf010804.hex should work), but prism2_srec has to be patched as the production data area ("PDA") has an invalid CRC. A patch like this should do the trick:
diff -ru hostap-utils-0.4.7/util.c hostap-utils-0.4.7-hacked/util.c
--- hostap-utils-0.4.7/util.c   2004-02-14 18:50:12.000000000 +0000
+++ hostap-utils-0.4.7-hacked/util.c    2008-04-18 21:32:17.000000000 +0000
 -372,7 +372,7 @@
-       return parse_wlan_pda(pda_info, 0);
+       return parse_wlan_pda(pda_info, 1);
Add to /etc/pcmcia/hostap_cs.conf (or equivalent)
card "PRISM ISL37101P-SSF Adapter"                                                                                                 
  manfid 0x000b, 0x7110
  bind "hostap_cs"
Then start the "cardmgr" daemon. It should detect and bind the card to hostap_cs, so you can see it as "wlan0" and "wifi0" in "ifconfig -a". You should then be able to load firmware using something like:
prism2_srec -gs wlan0 pm010102.hex
prism2_srec -gp wlan0 pm010102.hex
prism2_srec -rp wlan0 rf010804.hex
You can then configure and use as normal:
ifconfig wifi0 up
ifconfig wlan0 up
iwconfig mode wlan0 managed
iwlist scan
...or whatever

I'd sure like to try linux on my Tungsten C. Do you have link(s) and a how-to. Thanks!
