Summary:                    vprintk availability in kernels < 2.6.9
Description: 
in <zaptel-source/hpec/hpec_zaptel.h at line 36 :
#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,0)
	va_start(args, format);
	res = vprintk(format, args);
	va_end(args);
#else
	char buf[256];

	va_start(args, format);
	res = vsnprintf(buf, sizeof(buf), format, args);
	va_end(args);
	printk(buf);
#endif

this causes a compilation failure, and subsequent dmesg errors if zaptel
is modprobed on a 2.6.8-2 kernel. a quick google reveals that vprintk
support wasn't added until 2.6.9-rc1.

changing the line :

#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,0)

to

#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,9)

allows compilation and successful modprobe. forum user kerberos reports
that his system is able to use HPEC now.
