Zaptel-1.2.9.1 build: "Error 136"

I’m trying to build zaptel on an intel emt64 box, fc5. gcc-4.1.1-3, with /usr/src/linux2.6 symlinked to sources:

make linux26

gcc -E -D__GENKSYMS__ -Wp,-MD,/opt/asterisk/zaptel-1.2.9.1/.zaptel.o.d -nostdinc -isystem /usr/lib/gcc/x86_64-redhat-linux/4.1.1/include -D__KERNEL__ -Iinclude -include include/linux/autoconf.h -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -Wstrict-prototypes -Wundef -Werror-implicit-function-declaration -Os -mtune=generic -m64 -mno-red-zone -mcmodel=kernel -pipe -fno-reorder-blocks -Wno-sign-compare -funit-at-a-time -mno-sse -mno-mmx -mno-sse2 -mno-3dnow -fno-omit-frame-pointer -fno-optimize-sibling-calls -fasynchronous-unwind-tables -g -fno-stack-protector -Wdeclaration-after-statement -Wno-pointer-sign -I. -O4 -g -Wall -DBUILDING_TONEZONE -m64 -DSTANDALONE_ZAPATA -DZAPTEL_CONFIG="/etc/zaptel.conf" -DHOTPLUG_FIRMWARE -DMODULE -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(zaptel)" -D"KBUILD_MODNAME=KBUILD_STR(zaptel)" /opt/asterisk/zaptel-1.2.9.1/zaptel.c

I’ve also tried to build with MMX enabled:

make[1]: Entering directory /usr/src/kernels/2.6.17-1.2647.fc6-x86_64' CC [M] /opt/asterisk/zaptel-1.2.9.1/zaptel.o In file included from /opt/asterisk/zaptel-1.2.9.1/zconfig.h:9, from /opt/asterisk/zaptel-1.2.9.1/zaptel.c:40: include/linux/config.h:6:2: warning: #warning Including config.h is deprecated. /opt/asterisk/zaptel-1.2.9.1/zaptel.c:188: warning: ?fcstab? defined but not used {standard input}: Assembler messages: {standard input}:3266: Error: suffix or operands invalid formov’
{standard input}:3267: Error: suffix or operands invalid for mov' {standard input}:3668: Error: suffix or operands invalid formov’

which I thought worked with intel.

Any help appreciated.
