I made the same observation here when installing 2.6.19 :

root@...nard linux]# make modules
  CHK     include/linux/version.h
  CHK     include/linux/utsrelease.h
  Building modules, stage 2.
  MODPOST 573 modules
WARNING: Can't handle masks in drivers/ide/pci/atiixp:FFFF05
[root@...nard linux]#

Hardware is quite oldfashioned.
Is there any relashionship ?
