The default iobase and irq for the ne2k_isa card are 0x300 and 9.
It should be possible to override both using the "-net" syntax like
"-net nic,model=ne2k_isa,irq=5,iobase=0x280".

-device ne2k_isa,irq=5,iobase=0x280

If i specify "-net nic,model=pcnet" i end up only with a pcnet nic. With
the above syntax i get a e1000 and a ne2k_isa. It also loads the e1000 rom.

Can you supply the full command lines. I'm a little confused about what you're reporting.

"qemu -device ne2k_isa,irq=10" and "info qtree" has e1000 and ne2k_isa.
"qemu -net nic,model=pcnet" and "info qtree" has only pcnet.

Maybe because of hw/pc.c:

       if (!pci_enabled || (nd->model && strcmp(nd->model, "ne2k_isa") == 0))
           pc_init_ne2k_isa(nd);
       else
           pci_nic_init_nofail(nd, "e1000", NULL);
