I'd say the price for the most elegant solution goes to Sam.  ;)

My slip-up was the OSS ac97_codec in 2.6.25-rc.

The other ones I found until now are:
arch/x86/video/fbdev.c
drivers/ide/ide-pnp.c (bug introduced in 2.6.25-rc)
drivers/ide/pci/cmd640.c (bug introduced in 2.6.25-rc)
drivers/ide/ppc/mpc8xx.c (bug introduced in 2.6.25-rc)
drivers/ide/ppc/pmac.c (bug introduced in 2.6.25-rc)
drivers/ide/arm/ide_arm.c (bug introduced in 2.6.25-rc)
drivers/ide/cris/ide-cris.c (bug introduced in 2.6.25-rc)
drivers/ide/h8300/ide-h8300.c (bug introduced in 2.6.25-rc)
drivers/ide/legacy/gayle.c (bug introduced in 2.6.25-rc)
drivers/ide/legacy/buddha.c (bug introduced in 2.6.25-rc)
drivers/ide/legacy/falconide.c (bug introduced in 2.6.25-rc)
drivers/ide/legacy/macide.c (bug introduced in 2.6.25-rc)
drivers/ide/legacy/q40ide.c (bug introduced in 2.6.25-rc)
drivers/media/video/v4l2-int-device.c (bug introduced in 2.6.25-rc)
arch/arm/kernel/arthur.c

Most likely none of them is modular in the Fedora kernel and/or 
available on the architectures Fedora supports.
