The new code makes
probe process("/lib/libc-2.5.so").function("*").call { }
probes work well enough to insert them all. It turns out we
later get
"Task died at uprobe probepoint: ... probepoint = 0xaddr"
messages which I'm tracking down.
As for x86-64, we need first-byte-0x64 treatment:

3c2ea990a0: 64 8b 14 25 94 00 00 mov %fs:0x94,%edx
3c2ea990a7: 00
3c2ea990a8: 83 fa 00 cmp $0x0,%edx
3c2ea990ab: 89 d0 mov %edx,%eax
