4 out of 5 eggsWorks

Pros: Worked with Debian Lenny. It is necessary to append "8250.nr_uarts=10" (without quotes) to the Linux kernel command line (e.g., in /boot/grub/menu.lst or in /etc/default/grub) so that the kernel expects a high enough number of serial ports. 10 is chosen above assuming 2 built-in serial ports. I'm using mine in an HP ProLiant M110 G7.

Cons: In my system, the mapping from physical ports to /dev/ttyS* is as follows:
Cable 1 - /dev/ttyS4
Cable 2 - /dev/ttyS5
Cable 3 - /dev/ttyS6
Cable 4 - /dev/ttyS7
Cable 5 - /dev/ttyS8
Cable 6 - /dev/ttyS9
Cable 7 - /dev/ttyS2
Cable 8 - /dev/ttyS3
... not very intuitive.

Other Thoughts: I haven't had it in use long enough to comment on reliability.
