[ptmdm] - PCTel HSP MicroModem driver for FreeBSD

[Oleksandr Tatmanyants]

Hello,

I've got ICH4 modem in my Toshiba Portege R100 and really want  to make 
it working.
I've done as you recommended in the end of your letter and after little 
bit of work
manage it to build and load successfully but it ends up with

Feb 15 17:56:49 tats kernel: amrmdm0: <Intel ICH4> at device 31.6 on pci0
Feb 15 17:56:49 tats kernel: amrmdm0: could not find ioport base reg.
Feb 15 17:56:49 tats kernel: device_attach: amrmdm0 attach returned 6

Here is scanpci -v

pci bus 0x0000 cardnum 0x1f function 0x06: vendor 0x8086 device 0x24c6
 Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Modem

  MAX_LAT   0x00  MIN_GNT 0x00  INT_PIN 0x02  INT_LINE 0xff

I've fixed unresolved symbols in the following way

objcopy --redefine-sym __udelay_R9e7d6bd0=DELAY \
        --redefine-sym kmalloc_R93d4cfe6=malloc \
        --redefine-sym printk_R1b7d4074=device_printf \
        --redefine-sym kfree_R037a0cba=free \
        --redefine-sym __const_udelay_Reae3dfd6=DELAY \
        --redefine-sym schedule_timeout_R17d59d01=timeout i8xxhal.o 
tmp.o && mv tmp.o i8xxhal.o

The system itself is 6.0-STABLE as of February, 1 2006.

Could you please appoint me what can be done to solve this problem.

Thank you very much in advance.
