Installing a kernel package (locally built using make-kpkg) with
a VFAT /boot does not show any problems here:

root@pi:~# mount | grep /boot
/dev/mmcblk0p1 on /boot type vfat /(rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro)
root@pi:~# dpkg -i linux-image-3.12.6-rpi+_2014010201_armhf.deb

Done.

 Hmm. There is a symbolic link /lib/modules/3.12.6-rpi+/build
 However, I can not read it: No such file or directory
 Therefore, I am deleting /lib/modules/3.12.6-rpi+/build


 Hmm. The package shipped with a symbolic link /lib/modules/3.12.6-rpi+/source
 However, I can not read the target: No such file or directory
 Therefore, I am deleting /lib/modules/3.12.6-rpi+/source

Running depmod.
