How comfortable are you with modifying the code?

Take a look at rancid 3.6.2 - sub ShowFlash in lib/rancid/ios.pm looks for
  if (/(\d+) bytes (available|total) \((\d+) bytes used\)/) {
and changes the line to
 NN [GMK]B free

It doesn't seem like it would be too hard to change
 NNN bytes total (NNN bytes free)
to
 NN [GMK]B total (NN [GMK]B free)
