That bug is definitely present. Here is a dmesg output after suspend
with kernel-2.6.24.3-50.fc8.i686 when trying to access a floppy:

As you see from addresses this is from a different machine and
even different architecture.
Before suspend floppy works without any issues.
OTOH nowadays floppy is used so infrequently that this is hardly
a problem. A USB stick still mounts after a suspend.
