try reconfiguring your printer port from the BIOS. If the port is configured with ECP capabilities disable them, disable interrupts, DMA, etc..
In any case, good luck and let's hope they don't break more things with the next release.
For the record, adding
alias parport_lowlevel parport_pc options parport_pc io=0x378,0x278 irq=7,auto
to the end of /etc/modprobe.conf fixed the problem (as suggested at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=145151).
Thanks for your suggestions, Kam!
