 I updated my source tree and built a new -current/alpha kernel, and
 modload seems to work now.

 Hmm, it seems that a -current/amd64 kernel reboots my machine early
 in the autoconf process (sometime around when starting cpu1, I think,
 but the messages go by too fast for me to be sure). However, with my
 previous kernel from July 2:
 ld -R /dev/ksyms -e nv_lkmentry -o /usr/lkm/nv -Ttext 0x0 /usr/lkm/nv.o
 .text: addr = 0x0 size = 0x98b2 align = 0x40
 .shstrtab: addr = 0x0 size = 0x47 align = 0x1
 .symtab: addr = 0x0 size = 0x2f760 align = 0x8
 .strtab: addr = 0x0 size = 0x1dac6 align = 0x1
 .rodata: addr = 0x98c0 size = 0xb6b align = 0x20
 .eh_frame: addr = 0xa430 size = 0x16c0 align = 0x8
 .data: addr = 0x10bb00 size = 0x190 align = 0x20
 .data section forced to offset 0xbb00 (was 0x10bb00)
 .bss: addr = 0x10bca0 size = 0x11c0 align = 0x20
 modload: reserving 53248 bytes of memory
 ld -R /dev/ksyms -e nv_lkmentry -o /usr/lkm/nv -Ttext 0xffffffff80647000 -Tdata 0xffffffff80652b00 /usr/lkm/nv.o
 ld: section .eh_frame [ffffffff80651430 -> ffffffff80652b37] overlaps section .data [ffffffff80652b00 -> ffffffff80652c8f]
 modload: can't link `/usr/lkm/nv.o' creating `/usr/lkm/nv' bound to 0xffffffff80647000
