Tried installing the needed package? On SUSE it's called "linux32".

However, the more likely culprit is CONFIG_SMP: include/asm-i386/ptrace.h #if defined(CONFIG_SMP) && defined(CONFIG_FRAME_POINTER) extern unsigned long profile_pc(struct pt_regs *regs); #else #define profile_pc(regs) instruction_pointer(regs) #endif instruction_pointer is defined, profile_pc is not. > The only way I could find to set this option to n was hacking the > autoconf.h file...

Let me recall: you *did* succeed on your older fully-32bit Debian Woody system, right?
