[oe] how to know why bitbake will pick a wrong .bb file after providing PREFERRED_PROVIDER value

[srinredplano SP]

Hi ,
I am using DISTRO=arago  and MACHINE= omap3axon(same as that of
omap3evm ) to compile linux-2.6.22  kernel .

when I try to execute the following   command
tbake finds my .bb file and uses

$> MACHINE=omap3axon  bitbake virtual/kernel

wrong bb file is getting picked up . How to know why a wrong .bb file
is picked up(it always picks
linux-nokia900-2.6.28.10+gitr0+e93534addfc33a2fefbca13cb86a8f787e4b650c-r92.bb
file  ) and which  variable i have to override so that only my .bb
file gets executed .
Is there any thing else which I am missing . thanks  in advance
