It seems that latest versions of udev don't use permissions.d
files anymore. Instead, the ownership and access rights can be
declared in rules.d files with the MODE directive. At least,
that's the case on Gentoo, and looking at the udev-052 package
contents clearly show that /etc/udev/permissions.d is deprecated:

% qpkg -l udev | grep /etc/udev
/etc/udev
/etc/udev/scripts
/etc/udev/scripts/ide-devfs.sh
/etc/udev/scripts/scsi-devfs.sh
/etc/udev/scripts/cdsymlinks.sh
/etc/udev/scripts/dvb.sh
/etc/udev/udev.conf
/etc/udev/cdsymlinks.conf
/etc/udev/rules.d
/etc/udev/rules.d/50-udev.rules
%

So to make tpb work again, i've added this rule to my
/etc/udev/rules.d/10-custom.rules: 

KERNEL="nvram", NAME="%k", MODE="0664"

And after a reboot i have:

% ls -l /dev/nvram
crw-rw-r--  1 root root 10, 144 Feb 14 22:34 /dev/nvram

(oh, and here the read permission is enough to make tpb work)
