Implication is that it was working before the update?
If so, reboot and load the prior kernel (select from grub menu)
Then can use lsmod to show what drivers are loaded, although if it is a 
precomipled driver it does not show.
A reboot into the new kernel and a compare of the lsmod results should 
show the missing driver.
If it is pre-compiled into the kernel, one will need to examine the 
kernel source docs to see what they changed - this will need help from 
someone else as I've only done this twice and it takes some steps that I 
do not recall.
