I have found out that putting device hints into loader.rc in the form
of loader environment variables:

set hint.fdc.0.at="isa"
set hint.fdc.0.port="0x3F0"
set hint.fdc.0.irq="6"
set hint.fdc.0.drq="2"
set hint.fd.0.at="fdc0"
set hint.fd.0.drive="0"
set hint.fd.1.at="fdc0"
set hint.fd.1.drive="1"
set hint.ata.0.at="isa"
set hint.ata.0.port="0x1F0"
set hint.ata.0.irq="14"

does the job. 

However, if some Forth guru shows me how to tftp download and parse
/tftpboot/boot/device.hints, I'd be most grateful.
