micro systems
i386, ALIX.3C3 board (AMD Geode) with VGA and Award BIOS
I boot the ALIX.3C3 over dhcpd, it gets pxeboot_ia32.bin and displays the boot console.

I enter the following commands:

> load tftp:miniroot.kmod
> boot tftp:netbsd

The kernel loads and starts, the dmesg displays the various devices being attached.  But it does not show that it attempts to load a module, and so miniroot.kmod doesn't get loaded and the system has not root filesystem.
pxeboot i386 and instruct the booter to load a module before starting the kernel.

this problem is with the kernel and/or bootloader, not the installer.

 For some reason, pxeboot_ia32.bin is built with X86_BP_FLAGS_NOMODULES flag:

 pxeboot/Makefile:CPPFLAGS+= -DBOOTPARAM_DEFFLAGS=0x0c

 It works for me if I explicitly enable modules support:

 > modules enabled
 > load tftp:miniroot.kmod
 > boot tftp:netbsd
