intermec 2100's with lucent chipsets & dwepdump q's

anyone had any dealings with these ap's?   i'm currently collecting traffic 
on them with airsnort and dwepdump.  i've collected a few hundred weak iv's 
on keys 2 and 3, nothing on key 1 yet.

i'm wondering if i collected enough packets (> 1,500,000) will dwepcrack be 
able to break it?

do i have a dependency on having _some_ 1st key byte weak iv's - or will 
the brute force still be able to deal with it - with enough other key byte 
traffic?

thanks.
