Soekris net5501-70 problem with loading ATA modules on FreeBSD-Current

Hi all,

I am unable to dynamically load modules to support ATA disks on soekris net5501-70.

I boot via PXE diskless FreeBSD-Current.
In kernel config there are commented out options:

#device          ata            
#device          atadisk

After boot, I load modules:

 # kldload ata.ko
# kldload atapci.ko
# kldload ataamd
# kldload atadisk

so5501a% kldstat

12    1 0xc2f17000 4000     atadisk.ko

after that, in dmesg:

atapci0: <AMD ATA controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xe000-0xe00f at device 20.2 on pci0
atapci0: failed to add ata child device
atapci0: failed to add ata child device

And I am unable to access my HDD or CF. (see full 'dmesg' and 'kldstat -v' in attachment)


After compiling kernel with options:
device          ata            
device          atadisk

Everything works fine. 
But I would like to be able to load / unload ATA modules..
