Thanks Martin and Jerry. I followed the following steps :: a) Listed "lsinitrd /boot/initrd.img". It did not show any "/etc/modprobe.d/libertas.conf". b) Extracted "/boot/initrd.img" into a temporary folder. Obviously, no "/etc/modprobe.d/libertas.conf" was seen. c) Generated the required "/etc/modprobe.d/libertas.conf" with the content "options libertas libertas_disablemesh=1" in the tmp folder. d) Re-compressed the temp-folder to "/boot/initrd.img". e) Listed "lsinitrd /boot/initrd.img". This time, "/etc/modprobe.d/libertas.conf" was listed. f) Rebooted XO-1. g) Mesh-icons were still observed :( h) Note that I did this, without OOB (i.e. I was just wanting to test that whether this would work at all). I guess that there is something else we might be missing. So, I think that the only solution left now, is to put the "rmmod/modprobe" hack in olpc-configure. Would it be an acceptable upstream solution (the change in olpc-utils) ? Martin (Langhoff) / Daniel (Drake) ? Looking forward to comments and replies.

Doesn't OOB just sign what is in the kernel rpm? Think you would need to re-create initrd.img as needed then place the revised initrd.img into the image via OOB, to be signed by OOB.
