This seems to make better what I want:
__asm__ __volatile__ (
"lci %%r0(%%sr1, %2), %0\n"
"\textru %0,19,12,%0\n"
"\tdepw %0,15,12,%1\n"
: "+r" (ci), "+r" (pa)
: "r" (vba)
: "memory"
);

PS: I don't yet understand why kernel panicing when I try to get rid to
reserve 'ci' variable and use in place a gr as r19 (even if clobbered), the
produced object seems ok but resulting kernel panicing (even after a full
rebuild after a make distclean???)
