Bug#513915: firmware-bnx: no network device with xen kernel

[Casper Langemeijer <casper@bcx.nl>]

I experienced the same: The xen kernel can't load the module on my 
Dell PE 2950.

I think this is because the postinst file does "update-initramfs -u"

This only builds the 2.6.26-1-amd64 initramfs image. The solution is to
manually do build the initramfs image for the xen kernel using
"update-initramfs -k 2.6.26-1-xen-amd64 -u"

Or even better, a general: "update-initramfs -k all -u"

This is really is bug  #493863  and #494936 all over again.
