Yup.
T40p | T42p + Port Replicator II + Palm Serial Docking Station

No problems.
Works out-of-the-box and I never had a problem with it.

You have everything configured properly in the BIOS?

My boot-log:
Mon Jan 24 08:28:51 2005: Loading the saved-state of the serial devices... 
Mon Jan 24 08:28:51 2005: /dev/ttyS0 at 0x03f8 (irq = 4) is a 16550A
Mon Jan 24 08:28:51 2005: /dev/ttyS1 at 0x02f8 (irq = 3) is a 16550A
(ttyS1 is irda, if I remember correctly)

First message comes from Debian's setserial boot script, which uses the
following values to configure the 1st serial port:
/dev/ttyS0 uart 16550A port 0x03f8 irq 4 baud_base 115200 spd_normal skip_test
and sets these with the following commands in the setserial script:
	[...] read device args (from the line above)
	${SETSERIAL} -z $device $args
	${SETSERIAL} -bg $device

Kernel 2.6.10, serial built in. 
Config: Character devices -> serial drivers:
SERIAL_8250 is set
SERIAL_8250_CS is set (nothing to do with the dock serial)
SERIAL_8250_NR_UARTS is 4
SERIAL_8250_EXTENDED is set
SERIAL_8250_SHARE_IRQ is set
everything else is off.


What elso do you want to know?
