 I can't say anything about multilink PPP, but both the IOblix four port 
and the Commodore A2232 seven port serial card are supported under NetBSD:

msc0 at zbus0 pa 0xe90000 man/pro 514/70
2 loops before return.
msc0: Board successfully initialized.
msc0: Normal version detected (bfed:1)
iobl0 at zbus0 pa 0xea0000 man/pro 4711/1
com0 at iobl0 port 0x0108 ipl 6sc_frequency is 5529600
: st16650a, working fifo
com1 at iobl0 port 0x0100 ipl 6sc_frequency is 5529600
: st16650a, working fifo
com2 at iobl0 port 0x0118 ipl 6sc_frequency is 5529600
: st16650a, working fifo
com3 at iobl0 port 0x0110 ipl 6sc_frequency is 5529600
: st16650a, working fifo


That reminds me - I fixed a few things but I should check to make sure 
those fixes have been committed...

The A2232 can handle all seven ports at 19,200 with almost no overhead 
because of the 6502 which does all the work. If you swap the crystal you 
can use all the ports at 38,400 baud.

The IOblix can do up to at least 115,200, but obviously there's more 
overhead.
