[arch-general] Boot loaders for Linux that can also boot FreeBSD

my apologies for cross-posting this to several Linux mailing lists.
I need a boot loader for Linux, that is comfortable to use for my needs,
a Linux multi-boot with
trillions of Linux installs,
trillions ^ 2 kernels and
(trillions ^ 2) * 1024 entries with different boot options, so something
as GRUB 2 is unusable for my needs.
Until now I was comfortable with GRUB legacy, but now I add a FreeBSD
install to my machine and against the claims at
GRUB legacy does not boot FreeBSD (until now). I was thinking of
SYSLINUX, perhaps the most popular bootloader by Linux experts, but the
Wiki says it doesn't support booting BSD.
Since access to the freebsd-ufs partition by Linux is a PITA and Linux
is most important for me, I wont use a FreeBSD bootloader. I need easy
access to the bootloader's configuration file.
I still continue searching with Google.
Any hints are welcome!

Yes, ufs2_stage1_5 is missing, so when I tested
there was no error, but nothing happened, without the chainloader an
error 17, cannot mount selected partition appeared.
I wonder that so many *NIX users nag about Windows, but support to
access Windows files and to multi-boot with Windows is that easy. I
don't have Windows on my machine. I hope somebody is experienced with
multi-boot machines using different *NIX operating systems and will help
