Having built world and kernel from the 1.9.0 preview #4 sources, I found
this in the system boot messages:
DragonFly 1.9.0-PREVIEW #4: Sun May 20 22:43:30 BST 2007
...
Preloaded elf kernel "/kernel" at 0xc048b000.
Preloaded elf module "/modules/acpi.ko" at 0xc048b210.
link_elf: symbol r_esp undefined
I presume this means the acpi module wasn't loading; its sysctls were
certainly missing.
r_esp is defined static in sys/platform/pc32/acpica5/acpi_wakeup.c.
Removing the static...
% cvs diff acpi_wakeup.c

< static uint32_t r_esp = 0;

> uint32_t r_esp = 0;
..made the problem go away. But since this variable has always been
static, since v1.1 of this file, that doesn't feel right.
I did, by accident, build the kernel as well as the world with GCC v4.1,
so maybe that's the problem.
Apologies if this is user error, and I have a workaround with the
removed static for now.
