Interesting. It's hard to say exactly what's causing it without
a bit more context. I doubt that error message directly affects
the vlan configuration though. If you're really curious, set
VERBOSE=1 and DEBUG=1 in /linuxrc, backup initrd, and reboot.
You should get more verbose startup messages that will probably
include the command that causes the SIOCGIFFLAGS error.

There shouldn't be since /proc isn't a real filesystem. The
trick is to make the vconfig commands persistent across reboots...

The approach I would probably use is:
1) Copy 8021q.o into /lib/modules .
2) Add 8021q to /etc/modules .
3) Backup the "modules" package.
4) Use the "up" option in /etc/network/interfaces to run the
vconfig commands. As an example:
auto eth0
iface eth0 inet static
address 11.22.33.44
masklen 29
[..]
up vconfig add eth1 11
5) Test with:
svi network restart; svi shorewall restart
(After insmoding 8021q.o manually if necessary.)
6) Backup the "etc" package if everything works as expected.
There are also "pre-up", "down" and "post-down" options. Gory
