Cannot boot 5.3, 5.3-stable or -current on fujitsu-siemens amilo laptop

 Hi,
 
 I recently obtained a fujitsu-siemens amilo L1300 laptop.
I am unable to boot either FreeBSD 5.3 or -current with it and
booting fails with both acpi enabled or disabled.
 
FreeBSD 4.11 boots and installs fine (also, debian sarge with
2.6 kernel seems to able to boot too).
 
 The machine doesn't have a serial port so all information I can
provide about failed boots is a couple of pictures taken before
boot and after boot hangs. I have also a pciconf listing
and dmesg output from 4.11.
 
 This information is at http://www.suutari.iki.fi/fujitsu
 
 The message in the boot without acpi seems to complain about
interrupts, something like this:
 
BIOS IRQ 10 for 1.4.INTA does not match link 0x61 irq 5
Almost immediately after this boot hangs.
 
 With ACPI, there are some messages with AE_NO_HARDWARE_RESPONSE.
 
 Any ideas I might try ? The bios on this machine is a little bit odd,
there are almost no settings that could be changed (bios says it
is "insyde software mobilPRO bios 4.00.00 system bios R1.10").
 
    Ari S.
