We have:

;  DPMI utility functions

zero_regs:
        push    ax
        push    cx
        push    di
        xor     ax, ax
        mov     di, dpmi_regs
        mov     cx, 0x19
        rep
        stosw
        pop     di
        pop     cx
        pop     ax
        ret

...

dpmi_regs:

dr_di  = 0x00
dr_esi = 0x04
dr_si  = 0x04

dr_bp  = 0x08
dr_ebx = 0x10
dr_bx  = 0x10
dr_bl  = 0x10

dr_edx = 0x14

dr_ecx = 0x18
dr_cx  = 0x18
dr_cl  = 0x18
dr_ch  = 0x19
dr_eax = 0x1c
dr_ax  = 0x1c
dr_al  = 0x1c
dr_ah  = 0x1d
dr_efl = 0x20
dr_es  = 0x22
dr_ds  = 0x24
dr_fs  = 0x26
dr_gs  = 0x28
dr_ip  = 0x2a
dr_cs  = 0x2c
dr_sp  = 0x2e
dr_ss  = 0x30


Why are we zeroing 0x19 words = 0x38 bytes while there's only room for
0x32 bytes?


Right,
