Alt-SysRq & kernel 2.6.8: HOWTO?

[Piero Furiesi]

Hi all,   I'd like to enable "magic" alt-sysrq on kernel 2.6.8.   I noticed that 'make menuconfig' had no option about CONFIG_MAGIC_SYSRQ, so I manually added CONFIG_MAGIC_SYSRQ=y in my .config and recompiled the kernel, with no success.   Anyone got the hack?   Piero Furiesi
