Abit airpace wi-fi card and videocard incompability on abit ip 35 pro

[Moty]

quick config: [Q6600][4gb ram][Abit ip 35 pro rev 1.1][radeon hd4850 reference dising from asus ] [Delta GPS-650AB-A][abit Airpace wi-fi] WinXP64


I have a problem: motherbioard does not want to launch correctly with Abit airpace wi-fi card inserted in pci-e x1 slot . with radeon x1800 gto everything is okay
Problem only occurs when I'm using a radeon hd 4850.(reference design) The problem is: Motherboad starts, indicator shows "2b" (invoke video bios) and nothing happends.
After few reserts (2-3, may easilly go over 10 and over) motherboard finally loads and everything works fine.
wi-fi card and videocard not toches everything, nothing is short circuted etc.
Tried: different bioses (14, 16, 17 beta, 17) -same result, tried flash video bios from another manufacturer- same result, tried clear cmos, not overclocking any components, fail safe-defaults, optimized defaults, un-install all parts and install again, launcs outside of case, launch without hard-drives, launchig with no monitor connected, tried videocasd on lots of different configs(works fine, not tried with wi-fi card) etc, etc, only thing that helps completelly- removing airpace fi-fi card from system.
